Fix #135 - Don't save or use -32000 win positions
replaced "[Bob] legend rank" as game-end-trigger with "[Bob] ---RegisterScreenBox---" (#140)

=> "hide in menu" now hides the overlay only after the win/defeat screen was left.
moved position and size saves for all windows to Window_Closing of MainWindow. Checking for -32000 no longer required. (#135)
