Created spen_report struct

This will be passed to HID driver to imitate Pen
Disabled "warnings as errors" in test and wudfvhid

SPEN_REPORT struct uses bitmask with non-int types. This creates warning
in VC. Had to disable "Treat warnings as errors" for now to allow
building.
Added common.h include

To add SPEN_REPORT variable as part of device - will store last pen
state
added traceview.exe to project

For tracing. Added traceview.ini to .gitignore
