CxxBinder doesn't change string to SoundType for SoundSource and Audio

[EgorBo]

Audio.GetMasterGain(string) => Audio.GetMasterGain(SoundType)
SoundSource.SetSoundType(string) => SoundSource.SetSoundType(SoundType)

it's still string despite of my changes to CxxBinder: c4121a2

The issue is that the "currentParameterCount" should have been a zero.

That said, another fix that we have to do is turn the enums into C# like enums, so the use above of ToString() will not work once we go C#-names. So the right approach is to introduce an overload that takes an enum and passes constants based on it.

Actually, your enums already matched the C# style, but they wont work.

Because the constants in C++ need to be "SOUND_MASTER", and not "Master". Not sure that it is worth to do reflection + ToUpper() + string concatenation. Instead, let us follow my suggestion.
