Merge lp:~naufraghi/deja-dup/nice-monitor into lp:deja-dup/34

[Matteo Bertini]

This patche factorizes a common `nice_prefix` function in CommonUtils.vala and uses it both from utils and from monitor.vala

The old code in monitor was using an hardcoded legacy nice values and was never as idle as the new utils code.

Warning. These are my first lines in vala

Comments?

Sorry for late reply. This looks great, thank you! I had totally forgot we had a second nice check in monitor.vala. :)
