* Move various locate functions into the appropriate board item object.
* Unified best zoom for all frames derived from PCB_BASE_FRAME.
* Remove track.cpp as it is no longer needed.
* Dead code removal.
* Remove scary frame window pointer member from board item objects.
* Add draw bounding box to gerber draw item for debugging purposes.
* Remove most (not all) variables that were initialized but never used that
cause GCC 4.6 to generate a warning.
* Fix bug in schematic library editor best zoom calculation.
In Render, colors shown were the default colors, not the selected colors, when starting Pcbnew or Gerbview,
because colors were not updated after reading the config.
(WxWidgets 2.9.1 seems call setlocale( LC_NUMERIC, "" ) when wxConfig read doubles stored in config, but forget to back to current locale.)
Note: perhaps there are some dialogs that need this call to SetLocaleTo_Default() ).
* Minor code cleanup in pcbnew/netlist.cpp
