Unmaintained [XenMax] - Prefix Filter 2.1.8

A cool little addon. Sure, XF already allows users to filter threads by prefix, and it's not difficult, but I think an implementation like this, that puts the option in a place where users can't fail to see it, and which also looks nice, is the better way to go.

I have added this phrase for the title of selecter.
