Debian Testing smxi update

[techAdmin]

Now that the core stuff is working well, I'm fine tuning it more.

Latest feature: automatic detection of testing based on some regex of apt sources.

If you have no sid / unstable repos (not counting sidux, opera, skype, multimedia), and you do have testing / lenny repos, it will set global values to use testing data instead of sid data.

This is especially useful in the warning section, and the holds as well. If detected testing only, it will give different hold/ warnings than for sid/sidux.

This is a neat solution, I'll need to fine tune it a bit over time to add to the blacklist of irrelevant repos like opera, skype, etc, but this is a good start.

it will always default to sid if it can't detect any standard testing sources in apt sources.
