Shadowdancer for Shadowdark (new class)

 I have started poking around with shadowdark classes a bit so here is the first draft of a shadowdancer class for shadowdark.

Shadowdancer

Rogues who have been touched by the darkness of the shadow plane.

Weapons: Club, crossbow, dagger, shortbow, shortsword.
