* 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.

finished Draw functions for aperture macros.  Now aperture macros are drawn correctly.  Known bug: aperture macros having parameters are incorrect: parameters are not read correctly. Work still in progress.
