Read config from supplied opts, if specified
Fixed issue 103. Created a meta-store object store in order to save udpate_seq value on browser refreshes so that we don't have to call api.changes.

By removing the call to api.changes, we no longer have to do a full table scan to get the latest update.
Style fixes, added semicolons.
