Update osx/plist library to use OSX::PropertyList and OSX::PropertyListError
PropertyList module kept for backwards compatibility, produces warning on first method call, forwards all calls to OSX::PropertyList
PropertyListError is now gone for good (I can't think of a good way to hook into const_missing for this)
Note that internal usage of PropertyList now needs to be updated to use OSX::PropertyList

Changed:

U   trunk/Tools/plist/plist.c
U   trunk/Tools/plist/test.rb
