External Deps: Minimal Python dependency

[Sebastian Pölsterl <marduk k-d-w org>]

Hi!

As mentioned in [1] sqlite is a blessed external dependency now. I want 
to use sqlite for Deskbar-Applet, too. Because, Python 2.5 has a 
built-in sqlite module I suggest increasing the minimal version to 2.5 
from currently 2.4.3 . Of course, Python 2.5 has more benefits [2].
