Added support for enum overrides.

Browse source 
Enabled enum overrides in the CL and ES generators.
Function parameters now follow enum overrides (for example, if function Foo takes enum Bar and enum Bar is overriden to Baz, this change will be reflected on function Foo).
Changed default CLGenerator settings to not generate debug helpers.
