Jonathan Gordon a22749b5c6 FS#9525 - The list for the quickscreen items chooser turned out to not really be usable so try this instead. 
Settings in the menus will now have a context menu where you can reset the setting and if its OK to put it on the quickscreen there will be options there to put it on it.

Also, ban last.fm and cuesheet support settings from the QS
