Subject: mi: fix cursor warping screens

The server was processing ET_RawMotion type when the cursor was wrapping to
another screen and getting wrong valuator values. This fix such issue
considering only ET_Motion, ET_KeyPress, ET_KeyRelease, ET_ButtonPress and
ET_ButtonRelease types when the cursor detects a new screen, keeping the
"normal" processing of device events.
