Add new enemies #3

Add a few new enemies.

Some ideas:

• Lobsterfolk Druid - Can cast a single debuff spell. Can only fire spell in a straight line and at range.
  • Possible effects:
  • Player's next three attacks reduced in strength by 1.
  • Player loses a random one of their blessings from the list.
• Lobsterfolk Wizard/Archer - ranged attacker. Can't attack at range 1.
• Some sort of enemy that does more than 1 damage.
• Maybe a wall clinging enemy.
