• [x] Not Storing Asset Symbols
• [x] Only storing first owner_key, active_key, posting_key, memo_key

• [ ] fragile syncing behavior, unable to recover from steemd hiccups
• [x] sbds must also index virtual ops
• [ ] Add methods to sbds to replace account history in steemd
• [x] Data too long for column 'body'
