Removing ability to open ccbproj files to open projects.
Sandbox is preventing access to other vital files.
The .spritebuilder extension should be the only way to open projects now.
CCBProj file extension removed as registered Spritebuilder file type to remove open with option in finder and other applications.
Spritebuilder folders are registered as document packages now.
Double clicks will open the project in SB.
