## About The Pull Request
This PR adds a !!!FUN!!! bomb payload to the blackmarket, which, upon
detonation, transmutates all terrain in a range like the dimensional
anomaly would. You can also select the dimensional theme to use by using
it in your hand.
I believe however, this thing should cost a fuckton to get and only show
up occasionally. 8k to 10k was my original idea, but I think that's
perhaps not high enough given its flagrant potential. Perhaps I should
also make it so the more dangerous themes yield a shorter range than
others. Suggestions are welcome.
Screenshot of what happens when you don't set the theme:

This PR also turns dimension themes into singletons so we access them
more easily. Nothing to write home about.
## Why It's Good For The Game
The black market could always use some extra thingy or two anyway, and
this thing could either be a source of emergent gameplay, or a recipe
for a disaster. Perhaps second to the Big Slappy for how funny it could
be.
