Patch by Simon Lees simon@simotek.net based off a earlier patch
by Tomas Cech, this patch does 2 things,
1. In both xdg-su and xdg-terminal enlightenment is detected but then
   no action is performed, this patch performs a action in these cases
2. Rather then performing the generic action specific enlightenment 
   actions have been added to use terminology rather then xterm as it
   is essientially the enlightenment terminal emulator and matches the
   terminology theme
