* reverted clock ( --<| ) as it is commonly used for inverted clock in x-USSR
* nonlogic       ( ---X ) for non-logic pins of logic ICs (commonly used for power and timing RC pins).

Preparing work on trapezoidal pad DRC: cleaning code. some comments and translations added in drc.cpp. uncrustify drc.cpp

Added hotkeys editor from David Turner, with a lot of enhancements and fixes
Added pins connections info in intermediate netlist for each compoment. This is redundant, but some netlist formats (ORCADPCB, PSPICE) are very easy to create with this redundant info.

Pcbnew: Added move and rotate hot keys in board editor. hotkeys.cpp code cleaned. Fixed a bug that can crashes Pcbnew when switching track posture.

Updated boost::polygon from http://svn.boost.org/svn/boost/trunk/boost/polygon (boost 1.44) Seems fix some issues.

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

Fixed a minor issue when creating a netlist. for nets having global labels, global label names were ignored when naming 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.

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 

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

factor some pioneering code into a the stable building block class DSNLEXER, generalize expected valued for name and value within the template field parser.

fixed bugs 593546  ( 'Update module' in module editor becomes sometimes unavailable after undo ) and 593547  ('no' confirmation in module editor overlaps modules)
