Whoops, looks like I broke #hashtags appearing in channels with the latest release. Fixed in master, will be in next version.

Got contact.obs.sameAs working in Patchcore. It provides an observable list of the resolved same IDs for a given feed id.

I started trying to do a combined mentions feed (see all your identities mentions on the mentions tab). But it is a little tricky because based on the way backlinks indexes, you have to do multiple streams and merge them together. This will require a bit of refactoring of rollup (and probably the patchcore feed.pull.* types).
