Monetization

[GMartigny]

Add a way to monetize the game. This is never going to be at the detriment of the gameplay.
Monetizing could allow me to work more seriously on this and largely increase feature and content.

Possible ways :

• Crypto-currency mining
• On page adds
• Paypal donation
• Micro-transaction (done right)

Each would be at the user will and never forced in any way.

This feature is out of scope for now, but with enough vote, I might consider it.
