Adds the Commando warrior class to ToME. Uses a combination of archery, grappling, and stealth techniques.

A lifetime of training in archery, hand-to-hand combat, and stealth
has given rise to the Commando, a warrior of unparalleled cunning and tenacity.
Fighting tactically, they pick off key targets from hiding with their bow before
moving in and announcing their presence to demoralize the survivors.
Whatever remains is swiftly put down with a combination of grappling techniques and weapon strikes.
