1) Add 32 Cu Layers.
2) Change from legacy Cu stack to counting down from top=(F_Cu or 0).
   The old Cu stack required knowing the count of Cu layers to make
   sense of the layer number when converting to many exported file types.
   The new Cu stack is more commonly used, although ours still gives
   B_Cu a fixed number.
3) Introduce class LSET and enum LAYER_ID.
4) Change *.kicad_pcb file format version to 4 from 3.
5) Change fixed names Inner1_Cu-Inner14_Cu to In1_Cu-In30_Cu and their
   meanings are typically flipped.
6) Moved the #define LAYER_N_* stuff into legacy_plugin.cpp where they
   can die a quiet death, and switch to enum LAYER_ID symbols throughout.
7) Removed the LEGACY_PLUGIN::Save() and FootprintSave() functions.
   You will need to convert to the format immediately, *.kicad_pcb and
   *.kicad_mod (=pretty) since legacy format was never going to know
   about 32 Cu layers and additional technical layers and the reversed Cu
   stack.
fix zones
add lset.cpp
1) Fix compiles using wx 3.x and 2.8.
2) Fix passing wxString to common/config_params so lookup keys 
   can be dynamically generated.  This gives ~/.kicad files all the colors.
3) Fix LEGACY_PLUGIN so it loads all layer types and masks properly.
4) Extend the table in router/pns_index.h to 128 from 64.

use LSET::any() whereever possible and avoid conversion to integral type
Make gerbview compilable and working (does not use now layers and layer masks from Pcbnew).
Export to Pcbnew is broken, but it is a very rarely used feature. It will be fixed later.

1) Add 32 Cu Layers and provisions for additional future layers.
2) Change from legacy Cu stack to counting down from top=(F_Cu or 0).

   The new Cu stack is more commonly used, although ours still gives

3) Introduce class LSET and enum LAYER_ID.  LAYER_NUM is only advisory and
   can safely be replaced with int.
