[PATCH] xconfig: Set keyboard focus to line edit whenever the search dialog opens

["Peter Kümmel" <syntheticpp@gmx.net>]

When after a search on a result is clicked the focus jumps to
the result list. So after closing and reopening the dialog the
field does not have the focus any more. This is annoying when
you press Ctrl-F and start typing for a new search because
the text shows not up in the edit field but gets lost. You
have to click additionally into the edit field to move the
focus to this field. With this patch the focus is always set
to the edit field when the dialog opens.
