Implemented Chariotbuster Byakzak

Corrected his level and gave him his 2hr ability.

Had to create an extra group of an Orcish Fighter because it needed a diff spawntype than the others in same zone to be retail.

I am uncertain of wiki's accuracy on this NM saying its 21-24hr, seems more likely it'd be a % chance of NM per panzer kill, but going with "what wiki says" till we have reason not to.
