Title: Prefix category methods with kg_

As per [Apple's recommendation](https://developer.apple.com/library/ios/documentation/cocoa/conceptual/ProgrammingWithObjectiveC/CustomizingExistingClasses/CustomizingExistingClasses.html), category methods should be prefixed to avoid name clashes.

Added `kg_` as a prefix for all methods.
