Jonathan Gordon 80cb3551eb Statusbar handling fixes. 
Fixes FS#9845 - %we/%wd wasnt working
WPS no longer resets the viewportmanger more than needed (was doing it twice/draw before)
screens can now enable/disable the statusbar easily ignoring the setting instead of needing special handling (fix for the radio screen coming soon)

minor glitch introduced in this commit... the statusbar in the WPS might disappear for a fraction of a second when it is entered, I need to track this down...
