HG Tier 2a Economy (Customizable Economy)

[CampbellCrowley]

This is planned to be a premium feature
This is an extension of #102

HG Game Makers will have the ability to configure prices for all game items, as well as individually control the amount of coins each user has available to spend in the game.

I potentially may also allow for the name and icon for the currency to be customized at this tier.

This is planned to be unlockable at the $3 Patreon tier, with the economy option set. (Subject to change)
