Fixes for bug 775.

lonsearchcat.pm was modified to take a new parameter, cleargroupsort, which
causes it to clear the GDBM file used by the groupsort.pm handler.
&catalogmode_output was modified to take two new parameters which identify
uniquely the radiobutton it produces and the resource the radiobutton
refers to.
The javascript function queue was modified to take two parameters which
correspond to the two new ones passed to &catalogmode_output.

groupsort.pm was modified to pass 'cleargroupsort' to lonspreadsheet.pm
when the 'new search' button is hit.
