Carrying messages

Date:Fri May 27 08:49:57 2022
You will now get a message as your "carrying status" changes (as seen by info %F). For example:

  > drop barrel
  You drop a small barrel.
  Your burden is no longer all that heavy.
A carrying field was added to the GMCP Char.Vitals message, corresponding to the above.

Thanks Jahara for the idea.
