Make TyphoonDefinition main header more clear

[alexgarbarev]

Move not used by user properties and methods into private haeders. For example: "initializer" and "initializerGenerated" properties. In other case user can be confues which method to use: "useInitializer" or "setInitializer"

The TyphoonScopes have become invisible in Swift. . . seems it does not like NS_Enum

[jasperblues]

Ahhhh. No, actually it fixes the scope in Swift.

Instead of TyphoonScopeSingleton, use TyphoonScope.Singleton

Great!
