Dependencies and Desktop Environment neutral system

[TAC one]

We should define a clearer list of dependencies and try to purge all desktop-environment specific code.
We currently use gksudo and (soon) gnome-open. We shuold understand how many dependencies we need to use that kind of code.

Also we use nautilus, because seemed not possible to use gnome-open to browse files with gksudo.
We really need an alternative.

gnome-open file:///home does work
there is 'xdg-open' in hardy

ie xdg-open file:///home

gksu is a different problem.... there is a xdg-su but its been removed
http://changelogs.ubuntu.com/changelogs/pool/main/x/xdg-utils/xdg-utils_1.0.2-6/changelog

we could mimic the behaviour of xdg-su in python short term until xdg implements what ever they are planning on

I guess we shuold also refactor platform that kind of code into a single module class, so we can have better control in the future.

 def get_desktop_enviroment(self):
  # Taken from orignal xdg scripts
  if os.getenv("GNOME_DESKTOP_SESSION_ID") != None and os.getenv("GNOME_DESKTOP_SESSION_ID") != "":
   return "GNOME"
  if os.getenv("KDE_FULL_SESSION") != None and os.getenv("KDE_FULL_SESSION") == "true":
   return "KDE"

  try:
   if Popen(["xprop", "-root", "_DT_SAVE_MODE"], stdout=PIPE, stderr=open(os.devnull, "w")).communicate()[0].strip().lower().count("xfce") > 0:
    return "XFCE"
  except:
   pass

  return "CLI"

We should refactor every Desktop Environment dependent line of code in a separate class. then we can use Factory design pattern to load load the right one
