Quick & dirty OSC in ogre.

Thanks to the great library of Ross Bencina, OSC can now be used in Ogre. It has to be turned into a lib, clearly, but I need to remove tasks from todo list.

To use it, got to polymorph-engine and copy the folder example.2.0/app/osc/.
It contains the oscpack library and a sender wrapper for Ogre. Receiver will come very soon.
