* Add support for multi-bang flashbangs
It also adds some randomness to 1-bangs as a side effect,
but I don't think that's a big deal.
Also adds flashbang documentation to wiki.
* Increase rate at which flashbang attenuates
Apologies for the magic numbers. I just tested a few out
until I was happy with the result. The radius could probably
afford to be reduced a little further.
* use max deviation in config, fix wiki file name
