Huge update graphics, names, and tweaks

  *Added unique names for each hero by giving them their own namelist
  which is kind of hacky, but I couldn't figure out a better way
  *Removed all dependencies on weapons and armor defined in conceptual
  balance mod, and instead defined them locally with the same stats
  *Gave Slug higher holy, and an AoE ranged posion attack. Has a crappy
  animation sprite currently, will fix in the future
  *Added Alexander and gave him a weapon that does dangerous amounts of
  AoE damage
  *Removed "blind" from the base templates so only certain Lodum troops
  actually have it
  *Reduced some resource costs, and moved the AP values closer together so
  that the troops don't scatter themselves so easily. I had a hard time
  positioning them on the battlefield in a way that just made micro a
  nightmare. Had to try to predict how quickly they would all move
  relative to each other.
  *Added graphics for faceless lord, vile stalker, shaman betrayer,
  alexander, and felix
  *Added two new heroes alexander and felix.
  *Fixed some missing descriptions
