- Finally completed the chain_objects enumeration and general encoding rule
- Implemented SpendTx and SignedTx... and I *think* they work now (at least my cheesy canned testing says they do)
- Finally decided which way I want to deal with trailing spaces in the advanced variants of GajuFormat
- Found a roughly system agnostic way to deal with secret key memory and added an api for using that (might need more, but that will be clear soon)
