Title: Fix descriptor error from getattr in EventDispatcher

The call to ```getattr``` in the attribute loop in ```EventDispatcher.__cinit__``` throws an ```AttributeError``` exception on certain types of descriptors (such as those generated by ZCA). Those descriptors should not be Kivy ```Property```s anyway (which is checked on the next line), so I wrapped the call in a ```try```/```except``` block to skip those descriptors.
