Feat: Added cursor price option to user and basic settings (#2655)

## Description:

Following the hotkey cursor price textbox addition of #2650, this
feature adds the option to enable and disable the visual feature via the
User Settings menu or the Basic Settings modal in game. Also added a
[new icon](https://thenounproject.com/icon/pay-per-click-2586454/) for
the Basic Settings modal from the Noun Project and added credit for it
to the `CREDITS.md` file.
