[PATCH] Fix for deleting last remaining filter

[Craig Routledge <webstuff craigroutledge com>]

Attempting to delete the last existing filter (Edit->Filters...), cannot be  
done because the OK button becomes greyed out after the Delete button is  
pressed.

It is caused by a "changed" signal issuing a callback to fe_action_changed,  
which resets the various buttons inappropriately for this case.  The patch  
simply moves the set_button_sensitivities call down two lines, below the  
responsible line:

  gtk_entry_set_text(GTK_ENTRY(fe_name_entry),"");
