This patch include MosArt devices into hid-multitouch.
MosArt devices now support mt-protocol B.
We also need to introduce a new quirk for mosart devices to support
their contactID.

Hi guys,
this is the integration of hid-mosart into hid-multitouch. Now, I'm just waiting
for quanta and we are done with the integration of the generic multitouch driver.
This goes on top of the PenMount patch.
Cheers,
Benjamin
