TG: Cleanbots now patrol by default on creation, and will now clean up dirt.

Silicate was removed, as it didn't work properly and wasn't even useful to begin with.
Smoke will now create vastly less glows and shit, hopefully reducing server crashing capability.

The above is all credited to Sieve!

Foam was nerfed. I actually forgot to improve the janitor's cleaning grenades, so that's coming in a moment.
