Print correct event names for events sent via SendEvent requests

The high bit of an X11 event id is set to 0 for events generated by the
server, 1 for events sent from another client via SendEvent requests.

Previously xscope printed:
                         ..............EVENT: **INVALID** (150)

Now it prints:
                         ..............EVENT: ConfigureNotify
                                      source: SendEvent
