Add advertisements

[loegering]

It would be interesting to rig the game up to advertisements whether we launch it or not just to see how that might look.

At this point, I'm thinking we rig it into the event engine that players can opt into for better luck or returns on the event the trigger. Ideally, it is a banner ad that displays with the event results, but it would be interesting from an implementation standpoint to use video ads too.

This task would include investigation on tools that generate ads, how their API may be used in our event generation API, how it will be displayed in the game, and how it mechanically impacts the game results. Then finally implementing it in a manner that can be disabled if they've paid $1 or something.
