Hooking back enemy units

[DrkSephy]

This pull request does the following:

• Hooks up various enemies that have animations, etc.
• Gave all enemies proper weapons.
• Tested all animations.

Changes to come:

• Randomized items and stats for all units.

Discovered bugs:

• Having >=10 units in total on the map seems to affect the unit queue, with the main character not being the first unit. More specifically, the last unit in the party array will always become the first unit in the units array. See the screenshot below for reference:

Merging for now. We'll need to address this issue immediately.
