Beta release of COODBMS

Finished updating the docs and made the release. COODBM 0.3 is out.

Now it's back to CowDb to work on the 1.1 release. Then a bit more work on COODBMS before (finally!) starting JOODBMS.

JOODBMS is going to be dealing with high-level architecture to provide a flexible structure for managing Journals. I suspect that there will be some heavy lifting involved and I want to take care that COODBMS will be able to meet all the requirements of JOODBMS--which is why streaming will be added to COODBMS.
