sending a sequence number with enter messages. screens use that sequence number in clipboard grab and data messages. the server uses the sequence number to order messages across clients. also changed secondary screens to send clipboard updates on leaving (or when grab occurs when not active) instead of on a query from the server. primary effectively does the same. the query message has been removed.
