Subject: Re-implement XClientMessage handling so that we can feed screen_find
 and client_find valid resources as needed, relieving the need for screen_find
 to ungracefully handle invalid root windows. Removes a long standing XXX. 
 Should theoretically allow XClientMessage handling on more than one X screen.
  Alter callers of screen_find to handle failures.
