Regex match for stash affinities

Just saw Ziz and Mark talk about having more affinities, and sorting rares and stuff. A Regex match for affinity on premium tabs would allow us to roll our own affinities for sorting rares and a lot of other things. Even just one per tab would be really useful. The match can be done client side, and shouldn't be hard to implement.

This seems like a very good idea. Have the option to create our own regex filters for tab affinities? Yes please. It could be implemented with "first matching filter sends the item to the corresponding tab" to keep it simple, or with added checkboxes for basic item type filtering to supplement.
