Add master dashboard reporter and settings UI

- New reporter module that pushes firm stats (total accounts, accounts
  traded, in trade) to a configurable master dashboard every 30 seconds
- Add Instance Name and Dashboard URL fields to the settings page
- Register master_dashboard_url and instance_name in settings API
- Seed default (empty) values for new settings in db
