[OGDev] Spam remover tool

[Clair]

Thanks to Tom, I've now completed v1.2 - change being it now checks for 
certain keywords in the category/locale list, rather than for "Great site!"

There's a small chance some spam will be missed, or there will be false 
positives, I'd appreciate any reports of these.

Of course, I agree totally with Dom's view that we ought to be 
preventing spam from getting there in the first place, something which I 
think having real user registration will help with. (We can do things 
like moderate IP edits, allow certain users to moderate, etc easier.)
