Browse Source 
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

the server.  primary effectively does the same.  the query
message has been removed.
