[pnpgm] Mournaths' actions

[Gilbert Isla]

Being on watch when the creatures are spotted and noting their nature,
Mournath will ready his melee weapon, but also reach back and remove a
burning piece of lumber from the fire [ignore if we didn't set a watch
fire for some reason]. If there is time, Mournath will cast Bladesharp
on his broadsword. Also, he'll shout to any that aren't already awake
IC "To arms! To arms!"
