Summary: The Google style guide is neutral on whether there should be a space before the protocol list in an Objective-C @interface or @implementation. The majority of Objective-C code in both Apple's public header files and Google's open-source uses a space before the protocol list, so this changes the google style to default ObjCSpaceBeforeProtocolList to true.
