Organize some menus like Octopi.

[DrewNaylor]

For example:

• File
  • Refresh cache (Ctrl+R)
  • (separator)
  • Install package from manifest...
  • (separator)
  • Exit
• Tools
  • Sources editor...
  • (separator)
  • Options...

Most of the rest of the menus will be more like Synaptic, though.

Nah, the refresh cache button is under Package list, though the rest looks good. Maybe a button to start CMD in the File menu would be useful.
