[pnpgm] go thru wall

[Alex Koponen]

Seeing that the Vong have figured out a way to leach magic Z'leyra 
quickly goes thru the nearest wall (presuming that it won't be able to 
follow her thru the wall) to prevent her spells (and casting ability) 
from being drained dry. Mentally informing Will of the problem she goes 
on to scout further, avoiding the Vong with leather-strip magic leaches 
that have proven able to drain magic.
