relevant starting to port to peercoin commits

[FuzzyBearBTC]

There are two things that are relevant to you, though.
OmniLayer#84 splits up how we do balance queries. You'd want to add Peercoin querying similarly to how I added BTC balance queries. That'll be merged later today.

Also, I started splitting apart the transaction parsing loops so that multiple coins can be processed, but ended up not needing it, yet. You may find that work useful as well: https://github.com/curtislacy/omniwallet/tree/Btc-Parsing-Loop-InProgress
