Very minor other fixes.

Changes for CvPcb to eeschema stuff file: the stuff file generation from CvPcb is removed. Eeschema now imports footprints names from the .cmp usual file created by CvPcb or by Pcbnew (Why to use 2 file formats for the same thing?) .
Pcbnew: in netlist dialog: The user now can choose between the netlist and the .cmp file to import footprints names.
Therfore no need to delete the .cmp file when exists to use only the netlist.
This is useful for users who use CvPcb only once to fill footprints fields in schematic, and after edit/modify the footprints fields in schematic outside CvPcb.

Pcbnew: fix a very old bug in DRC, pad to pad drc tests: sometimes a test between a rectangular pad and an oval pad was skipped.
Segment Hit Test: enhanced detection near segment ends (noticeable for instance when clicking on short tracks in Pcbnew.
Remove duplicate code about segment hit test.
remove unused file.

Eeschema: fix Bug #1102381 <eeschema: -cache.lib file not created the first time you save a schematic>

Still try to find a better fix for Bug #1100876, however I am thinking the bug is not in Kicad:
looks like a buggy version of wxWidgets is used, which sends sometimes an unwanted wxCommandEvent event,
when an event::Check() is called inside a function called by a  wxUpdateUIEvent event.

Enhance DIALOG_SHIM to optionally call SetFocus() after the derived class's constructor has been called, for wx 2.8 and wxGTK

Kicad manager: fix a recent bug: project tree not updated when kicad is launched by a command line with a project name to open.
pcbnew: export vrml:
* move dialog functions in a new file: dialog_export_vrml.cpp.
* fix coding style issues
* patch add from cirilo Bernardo.

* Improve MSG_PANEL_ITEM to handle message panel information.
* Create containers for passing message panel items between objects and
  the message panel.
* Rename EDA_ITEM::DisplayInfo to EDA_ITEM::GetMsgPanelInfo.
* Remove all direct manipulation of EDA_DRAW_FRAME from all objects derived
  from EDA_ITEM.

EDA_LIST_DIALOG: add a filter option to select names to display is list, from a  kamil zorychta's patch <kamil.zorychta@gmail.com>
Use wxFormBuilder to create EDA_LIST_DIALOG_BASE, like other dialogs.
Minor code cleanup (remove unused functions and coding style fixes) and minor bug fixes.

Eeschema:commit patch <Prevent Eeschema from opening the same file twice> with a small fix for windows.

Pcbnew: Add pcad2kicad pcb plugin, to import PCAD boards ( .pcb ASCII data file PCad 2000 format ) from Alexander Lunef

* Create new GEDA PCB plug in.
* Add support for opening GEDA PCB footprints with module editor.
* Make import footprint file dialog remember last selected footprint
  type during current session.
* Update module editor file import to use new GEDA PCB plug in.
* Let IO_MGR know about GEDA PCB plug in.
* Create a WHITESPACE_FILTER_READER to simplify parsing GEDA PCB footprint
  files.

Pcbnew: board editor: allows pad edition by hotkey 'E' (was accessible only by mouse button right click)
All: minor code cleaning and very minor bug fixes.

Because now there are 2 formats, board backup files extensions are .brd-bak or .kicad_pcb-bak instead of the old .000 extension, depending on the initial file format.

Add KiCadPcbFileExt global.

Also a minor cosmetic enhancement

Eeschema: Add hotkey 'U' to edit reference. Better filtering for  hotheys V, F, U: now the corresponding field is selected without selection list between component and the field.

Try to fix an unwanted left mouse release button event, when closing a dialog on a click or double click,
and therefore when the mouse butoon is released in the parent window
Minor other fixes.

which can eliminate a subsequent call to READ_LINE::Line() for a small performance gain.

Another constructor for FILE_LINE_READER which enables more consistent file open strategies, and only call setvbuf() when the file is at position 0

their type, by using the more abstract PLUGIN::Footprint*() functions.

This is an intermediate phase only, other changes will be necessary as library table support comes in.
Encapsulate usage of library path searching, since that will go away as library table support comes in.
Add FOOTPRINT_EDIT_FRAME::{get,set}LibPath() and FOOTPRINT_EDIT_FRAME::{get,set}LibNickName() functions
to provide this encapsulation.

remove -std=c++0x compiler option since nobody is ready for it, and accordingly back into auto_ptr from unique_ptr

Fix compil issue under MinGW: for an obscure reason the option -std=c++0x creates error in wxWidget code:
some functions used in wxWidgets ( like _strdup and few other) are not defined when this option is set. 
but the equivalent option -std=gnu++0x works fine so it is used under mingw instead of  -std=c++0x.
(Under Linux/OSX  the option -std=c++0x is used)

   This required the additional compiler command line option "-std=c++0x".

2) Switch to unique_ptr from auto_ptr which is C++ deprecated.

3) Change to new English layer names per mailing list discussion, see class_board.cpp.

4) When saving to *.kicad_pcb or *.kicad_mod, identify opportunities to use wildcard
   layer sets, for pads so far.

5) Switch to two std::string hashtables in pcb_parser.cpp, away from one wxString based one
   for layer names and layer sets mapping. One hashtable holds the mask, the other the index.
   Layer sets are only in the mask table.

6) Move "LOCALE_IO toggle" into PCB_IO::Format() since it is a public API function and
   caller should find it as convenient as possible to use.  LOCALE_IO should handle
   nesting OK in the case where public Format() is called from one of the Footprint*()
   functions.

7) Drop support for "export module to new library".  Creating new libraries will have to
   be handled in concert with library table entries, and we've talked recently about
   creating a better footprint library manager, one that resides in a DLL/DSO.  So
   this kind of functionality needs to be handled in there in the near future.

8) Change name of exported PCB_IO module/footprint to *.kicad_mod and not *.emp.
