Contentment 0.3.0/Persist 0.3.2 Released

The rewrite of the Contentment system has been completed and refined. This code is still very Alpha. Contentment is also not yet very useful as it lacks a security manager and other refinements. These I hope to have added for the next minor release.

The new release of Persist 0.3.2 has been made because there was a bug in the Memory driver that caused it to fail when a deletion was attempting on an empty table. This shouldn't be an exception and stopped Contentment from functioning, thus, the new release.
