Added [minimal, non-user-specific] Xcodeproj
Changed name to ProtobufStaticLinb_iOS and changed build settings so it all works
Completed namechange to ProtobufStaticLib_iOS
Added .gitignore that ignores per-user-data from *.xcodeproj files.  See http://stackoverflow.com/questions/49478/git-ignore-file-for-xcode-projects for the source for this information.
