Sharing custom character sheet template

[SpaceDiceMan]

🚩 Is your feature request related to a problem? Please describe

Currently every players needs to recreate a custom sheet themselves (or have the GM modify each individually for them according #82 )

✅ Describe the solution you'd like

The GM modifies a custom sheet template and shares that template somehow with his players (either through a link, (json-)file, or other method). [If possible of course within current Fari free state! Love Fari!]

another solution to this problem without changing anything in the code is to create an empty character sheet, export it and let players import it on their browser.

I've seen people do this in the fast and feel like it's a nice workaround for now
