ENH: Cleanup building of OS X bundle content

 - Fixes repeated rebuild of bundles by Makefile generators
 - Add special rules to copy sources to their
   MACOSX_PACKAGE_LOCATION bundle directory
 - Remove MacOSX_Content language hack
   - Remove EXTRA_CONTENT property
   - Remove MACOSX_CONTENT
   - Remove corresponding special cases in object names
