Fix #75, determine the RPC target (#93)

Browse Source 
* Fix issue #75, determining the command target

If you add the same networkbehavior twice to a gameobject,  only the commands in the first one work.

This can also happen if you have a base class,  you inherit it,  and you add more than one of the inherited classes to the same gameobject.

* Improve error message

* Fix issue #75 for all RPC methods

* Fix formatting consistency

* Fix build,  replace logDebug with Debug

* Use new NetworkBehaviours cache

* Use FindIndex instead than for loop

* No need for local variable

* use int instead of byte for simplicity

* component index are int now
