Initial code commit. Adds the original RPC from simplecoin and a stripped down apscheduler
Initial major refactor of the client outlined
* Each RPCClient services paying out a single currency
* Complete removal of flask components
* Implemented defaults for config values
* Split individual actions into more modular groups to allow better retry semantics
* Most methods now have proper return values, although don't all handle the failure properly
* Placeholders put in place for sqlite actions that need to occur
