Bug 774109 - Bootstrap support for OS X; r=rnewman DONTBUILD
This implements the OS X backend for the bootstrapper. It ensures that the system is in the proper state to build Firefox by installing required packages. This was tested with a fresh install of OS X 10.8. Basic support for OS X 10.6 and 10.7 is implemented, but not thorougly tested.
