Changeset 1558 for code/trunk/src/core

Message:

added support for isVisible() and isActive() to all objects.
those functions are provided by BaseObject, combined with virtual functions changedVisibility and changedActivity respectively.
use them, to make orxonox scriptable, say: to change the state of objects with 2 simple functions instead of changing all meshes and emitters and billboards of an object. don't forget to pass calls to changedVisibility and changedActivity to the parent class.

additionally there is a new function, isInitialized(), provided by BaseObject too. this returns true if the constructor of BaseObject passed the object registration. this allows you, to check whether an object was properly initialized or if the constructor returned (as this is the case while creating the class hierarchy). use isInitialized() in your destructor before deleting something.
