Optimisations and PEP8 compliance

[Foggalong]

• After the last commit it dawned on me that the script is detecting what desktop enviroment the user is using, even though it only really needs to check for XFCE or Pantheon. I gutted all of superfluous stuff and shortened the function name to make it generally a bit lighter.

• Various changes to make the script follow the PEP8 Styleguide. These include:

  • Removed trailing spaces
  • Comments formatted # COMMENT
  • Inline comments separated by 2 spaces
  • 2 newlines between each definition
  • Spaces around operators
  • Spaces in comma lists (item1, item2, item3)

  The one thing from PEP8 I haven't fixed is the line limit of 79 characters because it would require a bit more work in restructuring the functions.

Together these changes mean the line count is slightly more, but the file size is slightly less. I think that's it from me for changes for now :)
