Add ability to tag/search by TTRPG system

[cpennington]

It would be awesome to be able to tag and search by which tabletop RPG system was in-use in a given thread.

If you're not interested in that level of specificity, though, go ahead and close this. (If you are, I might consider coding up the feature myself, if I can find some spare time).

Good idea.

I don't know enough about tabletop systems to do it myself. For example, how many systems would we need to support to encompass 90% of all tabletop RPs? If it's no more than a dozen, then we could just add tags that only appear when creating/editing a RP in the tabletop forum.

If it's more than that, then it would make more sense as a dropdown box which the current naive tag system doesn't support. At that point it's probably worthwhile to think of rewriting the tag system to support arbitrary tags.
