Add Licensing Fee Module to Admin Interface

[AdamBLevine]

When a new installation of swapbot is deployed, the operator needs to be able to easily understand and pay the licensing fees they owe to Tokenly for their use of the platform.

Please add a new section to the admin interface for this purpose.

The module should simply:

• Count the number of currently paid bots on the platform each month
• Let the admin select how they want to pay the invoice (credit card, bitcoin, tokenly)
• Provide the appropriate info (Stripe form or pay-with-pockets) to let them make their payment
• Visual feedback confirming payment detection and confirmation
• A running total of how many Roadmap Tokens they'll receive at the end of the month (we're going to use the mass distributor first)

On the backend, we'll need a spreadsheet of all payments to do the distribution. 1 paid swapbot pays tokenly $1 worth of license fee which will earn 1 roadmap token.

We'll probably want to not start counting paid bots for licensing fee purposes until there are more than 2 paid bots on the service.
