Extract platform-specific code in a wxUIActionSimulatorImpl-derived class instead of keeping it in wxUIActionSimulator itself. This will allow determining which implementation to use dynamically (i.e. at run-time and not compile-time) to use later and already allows to get rid of an __WXOSX__ #ifdef in common code.
