Properly copy all event parameters in deliverMouseEvent()

Timestamp and capabilities were missing. One of the very special flick
test cases needs to be fixed, because setting the proper timestamp
will now generate correct velocities. A potentially dangerous, legacy
implementation of flick() has also been updated to match how QTestLib
works in Qt 5.
