I've disabled two functions that were causing issues with the recent
changes - one was the special handling of seals and their destruction
upon the letter being openned. The other was requring the letter to be
opened to write on it (it was messing with books and journals).

Hopefully both of these will be fixed and reactivated later on in the
month. For now though, they are down so this means every letter will
have a permanent seal.

Penned by my hand on the 16th of Lleian, in the year 258 MA.
