Added INI files to get UserTracker to initialize.

The INI files hardcode a path to drivers and it looks like you might need a driver for each
different type of hardware. My OpenNI2/Drivers directory contains a PS1080.ini file, which
probably corresponds to my PrimeSense. I don't know if this will work for other hardware.

Also note that the NiTE.ini file hardcodes a path to a data file inside the unpacked
NiTE-2.0.0 install (yuck).
