Add a way to retrieve values from .git/config files

Browse Source 
This introduces the PBGitConfig class. It is KVC compliant as far
as I can see, in that you can actually bind to it in IB and use
ValueForKeyPath to retrieve values. It currently only handles
strings; it should be possible to add functions to process
booleans and numbers to it.
