Add currency to character sheet

[stanavdb]

Currently the character sheet inventory does not show currencies. We'll need to think of a clear way to display the various depths of currencies possible.

Perhaps a system setting for renaming a core denomination, and then making custom denominations with values relative to the core one? Then a nicely formatted list for them on the sheet. This allows it to default to just marks like the system prefers, but the option for broams and the like as needed.

It's actually a little bit more complex as we don't just need to support spheres as a currency but have to be able to handle all currencies from the various Cosmere worlds. Have a look at the Actor data model to see how currencies have been modeled.

To add to that; available currencies are configured through the CONFIG.COSMERE.currencies property. (Which the world modules would add to using the api.)
