Don't break my stuff

Now with protection respect, and new crellm toothpaste.

The "let me live" release

Survival mode is now implemented, but protection checks may still be a bit wobbly.

Squishy

More silly bugs crushed, logic bombs defused and code sanitised.

bugfix

Small changes to remove silly bug.

First release version

Symmetool mirror is now ready for first release, although the code is far from clean, I believe it's tough enough not to destroy servers. Do not, however, take this as any notion of safety or stability ;-)
