This adds the ability for players to "tip" Godot games.
They get rewarded in the form of an icon that will be visible when commenting on the game they tipped.
More rewards will be coming in the future, some of them customizable by the studio.
Badges are implemented, the user could potentially get a badge for tipping.
The rewarded badge can be implemented so that the studio itself can set how the badge looks for tipping that specific Godot game.
Fees are applied.
