Subject: Persist transactions to config-manager

Transactions are now stored, and are never deleted, they only have their status updated.

We can add deleting later if we'd like.

I've hacked on emitting the new unconfirmedTx key to the UI in the format it received before, I want Aaron's opinion on where I should actually do that.
