bands searching function

Style is gonna be really hard. We have the tagging system in place, but it kinda sucks, and I doubt it's properly searchable.

Location and names should be less of a challenge, but still: not easy. I was actually planning to replace the current search system altogether, since it's pretty much useless. Maybe some content type specific search tools can be implemented at that point as well. Don't expect it for anytime soon though, I don't really have time to implement any new features at the moment
