(svn r7638) -Codechange: Remove special window ShowJoinStatusWindowAfterJoin and shuffle around

some code for SetupColorsAndInitialWindow. Because we know that after a successful
 load all windows are removed we can setup default windows in this function, and
 show ShowJoinStatusWindow in PACKET_SERVER_MAP.
-Setup the global _network_join_status for ShowJoinStatusWindow in the only two
 places where the function is called, instead of inside it.
-Turn the join status window into a modal window of the network window so it
 stays on top.
