With these changes we have zero errors and zero warnings with RECOMMENDED_FLAGS!

Most of the changes were adding @override for methods and properties in mixins. Apparently if you implement an interface you need to say @override for each method or property on the interface. This combines with our mixin strategy to the tune of needing to add @override on every non-private method and property.

I'm not sure this is intended behavior of the compiler. Filed google/closure-compiler#3137 to see if it is.

This is awesome! I have 1 comment though, as I think that will break projects compiling with TS 3.
