[pnpgm] sign language

[Alex Koponen]

Remembering the last time someone had an abysmal spell failure that 
involved the voice Z'leyra decides that it would be a good idea to use 
her sign language skill to communicate and avoid speaking for the next 
24 hours. So much for her using spells for awhile. She will also avoid 
other uses of her voice such as yelling or screaming.

When she thinks it may be better she will ask someone in the party to 
move out of hearing range and try whispering. If they signal that they 
can hear her she will know that the problem persists.
