Gerbview: Fixed compil problem in debug Mode. Pcbnew: try to fix an issue in export gencad  (incorrect rectangular pads)

Gerbview: Added support for gerber command   SR (Step and Repeat) and multiple MOIN and MOMM in file

      
      It follows the CMake wiki 
      
      http://www.cmake.org/Wiki/CMake_FAQ#Can_I_do_.22make_uninstall.22_with_CMake.3F
      
      and it should work if one
      compiles from the build directory (building all kicad).
      
      You can use it running the following commands from the kicad source
      tree root:
      mkdir build
      cd build
      cmake ../
      make
      (using root) make install
      (using root) make uninstall

Gerbview: added support forSF (scale factor), IO (Image Offset), OF (Offset) and MI (Mirror) commands.

Fixed a bug about Aperture Definition having parameters for an aperture macro. See Changlog for not yet supported RX274X commands. Having still problems with arcs in some gereber files.

* Break classes_body_item.cpp(.h) into more reasonable size bites.
* Rename classes_body_item.cpp(.h) to lib_draw_item.cpp(.h)
* Fix some unsatisfied header file dependencies.
* Add stubs to component library draw item base classe to handle editing
  internally.
* Lots of code cleaning.

* Changed wxPenStyle which is not define in wxWidgets 2.8 to int and
  renamed GRRect to prevent duplicate function definition in gr_basic.
* Add missing wxT() macros to strings in rs274x.cpp.

Some cleanup and fixes in gerbview. Cleanup gr_basic.* and added in gr_basic.* a minor modification coming from "EEschema selection.patch".

* Use C++ map in component library instead of boost::ptr_vector.
* Drop Boost pointer containers for standard C++ containers.
* Moved duplicate name user interface elements from library object to
  library editor.
* Added code to support direct addition and replacement of component
  alias objects into libraries.
* Removed temporary strings used to add and remove alias objects.
* Libraries only store alias objects, components now accessed thru alias.
* Simplify library API for adding, removing, and replacing components.
* Updated edit component in library dialog and library editor to reflect
  component library object changes.
* Fixed bug in library viewer when displaying alias name.
* Made a few header files compile stand alone per the new coding policy.
* Remove some dead code and the usual code formatting fixes.
