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.

Add *.kicad_mod as default import footprint extension.  Turn on all Cu layers for thru hole pads in case loading non-wildcard s-expression footprint files.

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.

pcb_calculator: fix a compil warning (gcc 4.7)

switch to new s-expression format for footprint exports, use english layernames for naked footprints, dodge conflict with pythons HAVE_GETC_UNLOCKED

can be parsed, since they do not have an overriding layer name map
like a BOARD does.

Avoid doubly looking up hashtable entries in m_layerMap.

Minor code reformatting.

* If this param is set to 0, the previous behavior is used.
* Else the solder mask is plotted as polygon, with shapes near than  this min width value are  merged.
Pcbnew in nanometer version: fix a serious rounding issue due to the fact dialogs were using 4 digits for mantissa.
* This is not enough for nanometer coordinates ( 8 are needed to display a value in inches),
*  so sometimes after closing a dialog, some coordinates were modified, although no new value was entered.
Minor other bug fixed.

Eeschema: fix an old bug: sometimes E hotkey (and some other' hot keys)  was editing a previously selected item, not the item under the mouse cursor
Templates: remove useless backup files

Here is a first cut at the 40pin booster pack template. I made 2
versions, BoosterPack40, which has the optional J5 connector and is
2"x1.7" and BoosterPack40_min, which is 2"x1.35" and leaves the
switches accessible.

switch from STREAM_OUTPUTFORMATTER to FILE_OUTPUTFORMATTER mostly throughout,and minor richio factoring

add class FILE_OUTPUTFORMATTER and use it in PCB_IO, since it is about 8-10 faster than STREAM_OUTPUTFORMATTER

Minor enhancement in popup menus for wire and bus.
Kicad: stm32f0discovery template: very minor fix.

fctsys.h: remove useless define.
Fix minor issues and add minor enhancements.

Fix a minor compatibility issue in .pro file for new boards, between decimils and nanometers versions of Pcbnew.

Kicad manager: project_template.cpp: accepts  lower and upper case HTML keywords (compatibility with libreoffice)
