munin_update plugin changes order of values very often. (with patch)

[quattro]

I've found this behavior in the munin version that comes with squeeze.

it turns out that the order of the hosts in the $UPDATE_STATSFILE ist rather random
and so is the order in the diagrams.
meaning: a host gets another color more or less every update.

a simple 'sort' added after the sed line fixed this for me.
the second sort is superfluous but I put it there because I'd like these 2 lines to look the same ;-)

here's the (very simple) diff:

Oops.

Sorry, I commited it in 6f0e6e2b4bf0caa36cef65028de24cf03c04ab5b without updating the bug.
