* 03_display_session_capplet.patch: display the session properties capplet, 
  the list is cleaned from the system services now and it can be useful 
  for users who want to start softwares with the session (lp: #802218)
* series: comment 80_new_upstream_session_dialog, the modified version never
  went in upstream git and has issues with gtk3, if the upstream dialog is
  not working fine in our desktop we should discuss how to maintain a custom
  session dialog in a better way (lp:807503)
