PoC bookmarking system built on perkeep

This system stores all bookmark metadata, as well as a full snapshot of the bookmarked page as it existed at time of bookmarking, in perkeep.  Saving the snapshot is optional to be compatible with this, of course, just remove some wget lines and use pk-put permanode instead of pk-put file --permanode.

The bmarks script tags as arguments more perkeep query operators. So run with no arguments it shows all bookmarks (title + URL) but you can also run, say `bmarks tag:article`

The bmark script takes URL then title, then all other arguments are added as tags.
