Multitouch Device: Support Dev Progress

[teh-nicKLess]

Correct transformations of pointer coordinates with activated projection are implemented for VRMouse. Transfer of transformation implementation to VRMultitouch is needed.

[teh-nicKLess]

Successful transfer of transformation code from VRMouse into VRMultitouch. Works.

Next step: create and manage multiple beacons for multitouch.

[teh-nicKLess]

VRMultitouch does now create and maintain a separate beacon for each "finger".

Next step: "dev.intersect()" in PVR-Scripts needs to support all those beacons, only supports the first one atm.

[teh-nicKLess]

Python Bindings adapted for multiple beacons. dev.intersect() works as intended.
