Mac:

Fixed gcc-4.0 compile error (cocoa)

Updated scons to build cocoa (32bit & 64bit) (Thx Jens Verwiebe for the patch):
- make sure right python is unzipped to app-bundle ( printing information at the end of compiling )
- make sure arch-setting appends needed flags ( depending on OSX-version obsolete sometimes but harmless )
- link correct frameworks depending on gfx-api ( cocoa/carbon)
- conscript prepared for cocoa objC-files
- link to openAL-framework, using the headers from blender-lib + the symbols in framework

Usage instruction:
The default build is Cocoa 32bit.
To change it, copy config/darwin-config.py to user-config.py in the blender folder, and edit:
- WITH_GHOST_COCOA & MACOSX_ARCHITECTURE variables to select cocoa/carbon, and the arch (i386, X86_64, ppc, ..)
- the libs options as usual
