Subject: [PATCH] Properly Cancel Usable Items
This fixes the bug causing cancelling PlayerInteractEvent to cause items to continue to be used despite being cancelled on the server.
For example, items being consumed but never finishing, shields being put up, etc.
The underlying issue of this is that the client modifies their synced data values, and so we have to (forcibly) resend
them in order for the client to reset their using item state.
