Revise TokenList2DsnLexer.cmake to take outCppFile and outHeaderFile optinally
    and enum mandatorily.  Standardize the script's invocation technique within
    all the CMakeLists.txt files.

netlist export speed optimizations, bug fix in NETLIST_HELP::FindAllInstancesOfComponent that I put in there yesterday.

  * 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.

minor code cleaning. fixed minor warnings in debug mode.

Added boost::polygon (experimental)
Added experimental zone fill calculations with boost::polygon
Added patches from Yury Khalyavin

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 naming this net.

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

Cleaning code: moved some help strings used both in toolbars and menus in a single file help_common_strings.h,
in order to avoid slightly different help strings for the same command, and avoid some not needed  translations.

* Continue component library class clean up and encapsulation work.
* Change hierarchical sheet label container to boost::vector_ptr.
* Encapsulate hierarchical label handling in hierarchical sheet class.
* Convert some missed occurrences of wxString::GetData() to GetChars( wxString ).
* Fix some minor code formatting issues.

    In netlist generation, changed the rule to calculate netnames of nets with labels:
    Previously, named nets (i.e. nets with local, hierarchical or global labels) have their name
    defined by the first label found in list.
    So net names could be changed without really changing the schematic.
    Now the names are calculated from the rules (by priority order) :
    1 - use the most top level labels in hierarchies.
    2 - use global labels first, local labels next (hidden power pins names are global labels).
    3 - use alphabetic sort (so, if GND and AGND are connected, the net will be always named AGND,
    and adding a VSS connection cannot change the net name)
    So power nets and nets that have more than one label cannot have their netname changed
    if there is no actual change relative to these nets names in schematic
