Added the "actor" property. Metakit backend not done (still not confident I know how it's supposed to work ;) Currently it will come up as NULL in the RDBMS backends for older items. The *dbm backends will look up the journal. I hope to remedy the former before 0.7's release. Fixed a bunch of migration issues in the rdbms backends while I was at it (index changes for key prop changes) and simplified the class table update code for RDBMSes that have "alter table" in their command set (ie. not sqlite) ... migration from "version 1" to "version 2" still hasn't actually been tested yet though.
