regenerating templates off of local db app
converting addon to use local db for syncing layer rather than profile change monitoring w/ event signalling. so far, works a lot better/smoother. no more need to POST /sync just because we detected a change and want to force sync (and no more associated race conditions). this cleans up a lot of event listeners/senders. also. removing pinning junk.
upping to 0.3.0 because of new local db changes. the old clients will not work on the new syncing schema, so need a larger version bump.
