Cleans noise files out of the Project Template tree.

Noise includes '.DS_Store', all files that include a '~' character,
and all user specific Project Builder information.   User specific
Project Builder files -- the files ending in '.pbxuser' -- will cause
a corrupted, but mostly working, project to be created from the
templates.
