Jonathan Gordon 4983d052a0 Remove to top/bottom quickscreen defaults. 
As constantly discussed in IRC, it is insane that dirfilter and party mode are defaults on the quickscreen, both have caused countless problems for users accidentaly enabling them.
This wont change anything for users who have changed their setting, only for people who left it default
