Mark Watched Videos for SpankBang

This is a relatively simple script to mark videos you've seen on SpankBang as watched. It works by building an IndexedDb store of videos from your account history, and then adds videos to its list as you open them.

Please be aware that this is a beta build, and as such is missing features. Future versions will include:

importing/exporting history from/to text
A clear history button
A hide instead of mark option
