redo how the statusbar updates are done. send the EVENT_GUI_ACTIONUPDATE event every time get_action() is called. The event wont be as realiable (timewise) as before, but seems to work better

This also fixes FS#9761.
Also set the lcd font back to the ui font from the debug screens which use sysfont
