* Make Pcbnew net list dialog honor escape key on Linux.
* Make Pcbnew swap layers dialog honor escape key on Linux.
* Layout and UI policy fixes for Pcbnew swap layer and net list dialogs.
* Layout and UI policy fixes for Eeschema plot dialog.
* Rename fpip.h to fpid.h.
* Fix FPID class compiler errors.
* Restore fpid.cpp to Pcbnew static library source list.

Eeschema: All fixed fields are now always saved in libraries. Therefore the footprint field can be set in lib (size, visibility) and imported in schematic with its predefined attributes, even if the footprint text is not set.

Very minor other fixes.

added option to allow zooming around the crosshair instead of the center; can be enabled via options or by holding alt while using the mousewheel

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
