updated the quickscreen's:

- use viewports
- dont change to system font, fiddle with item positions to make them fit small screens
- user customizable options (use the .cfg settings "quickscreen_left, quickscreen_right, quickscreen_top, quickscreen_bottom" for the name and the .cfg name for the setting you want to use. it can be any except the string settings... (e.g. quickscreen_left:talk menu)
- a top item! if there is none set the up button will exit the screen
