V1.11.1: HP and money are the DM's to change

- A player can no longer heal or hurt their own character: the Damage,
  Heal and Temp HP controls on the sheet are the DM's, and the server
  refuses the change from anyone else. Players still roll their own
  death saves.
- A player can no longer add money to their own purse or write it off:
  recording a gain or a spend is the DM's, in any coin or in cash, on
  the sheet and on the server.
- Players still exchange gold, silver and copper on the sheet, give
  money to another character, and buy from or change money with an NPC.
- All packages at version 1.11.1.
