* Now link with XML support within wxWidgets.
  * Start of export the generic netlist in XML.  Still need to rework the chain
    loaded netlist plugin.
  * OBJ_CMP_TO_LIST class now uses a std::string to hold the 8 bit string m_Ref,
    but hides this behind accessors which provide for both Unicode and 8 bit
    set and get functions.
  * build_BOM.cpp retains the selected filename on subsequent runs as a default.
  * Code cleaning, especially in build_BOM.cpp.

Fixed some issues with wxWidgets 2.9.1 (fixed Gerbview and Pcbnew crashes under Linux when starting. Could explain also crashes under MACOSX)
Code cleaning.
pcbnew:
    Added experimental zone fill calculations with boost::polygon
    old file zones_convert_brd_items_to_polygons.cpp has now 2 versions:
    zones_convert_brd_items_to_polygons_with_Boost.cpp use boost::polygon to calculate filled areas
    zones_convert_brd_items_to_polygons_with_BKbool.cpp use kbool (code cleaned).
    >>> to use boost polygon version:
        call cmake with option: -DUSE_BOOST_POLYGON_LIBRARY=ON
Eeschema: added patches from Yuri Khalyavin

Added boost::polygon (experimental)

finished replacement of Get_Message (not very useful) by wxTextEntryDialog

item.

Fixed compil warning under wxWidgets 2.9.1.
File beautification
Statring using wxTextEntryDialog instead of Get_Message (because Get_Message does not handle properly cancel option)

Fixed a minor issue when creating a netlist: for nets having global labels, global label names were ignored when searching a name for this net.

Pcbnew:   Added grid origin patch from Lorenzo Marcantonio.   Converted set grid dialog from DialogBlocks to wxFormBuilder,  and added in this dialog the grid origin parameters settings.

dixed very minor compil warnings

inches and mm, the industry is crazy enough to force us with mixed
design. For example I routinely use imperial units for track size and
clearance, but drilling is strictly a metric issue...

So I added a little parser to recognize a suffix specification in the
unit text boxes... so you can put in things like:
1in (1 inch)
1" (idem)
25th (25 thou)
25mi (25 mils, the same)
6mm (6 mm, obviously)

The rules are: spaces between the number and the unit are accepted, only
the first two letters are significant.

As a bonus, it also recognize the period (.) as a decimal point
substituting it with the correct locale character (there was a wishlist
for it, IIRC). Most useful for number pad fans :D

dialog_edit_component_in_schematic: moved "Reset to Library Default" Button. This command is now undoable.
Fixed bug 603481

fixed bug 603481. Better bitmap2component look. fixed some locate problems for footprints using polygons (mainly created by bitmap2component)
