wrapMethod causes issues with callbacks

[jekky]

• @wrapMethod creates one method for every wrapper, but it looks like the game invokes every cb method on a class, so all of the wrappers get invoked
• cb methods should take exactly one argument and it's type should extend Event, this could be enforced by the compiler

[Pavel Siberx]

cb methods can have different signatures, Event based callback is just one variation that can cause issues with wrappers
