#207 DiddleSnap interfers with FindHack

[Florent Pillet]

When DiddleSnap is active, it improperly clears the notifyPBP->handled
flag. This flag is a collaborative flag, meaning that you are not supposed
to clear it. You are only supposed to set it to True. Actually, FindHack sets
it to False when a vchrFind virtual char goes on the queue, to indicate to
the system that it has handled the event and displayed a Find dialog.

The solution, for DiddleSnap, is to not touch this flag as you don't want to
interfer with other hacks.
