Added appearance.2da to fix crashes

[glasnonck]

Fixes #68.

• Added a custom "appearance.2da" that will be copied into Override\ at the start of randomization. This new table adds models and textures to the j column, which controls how the Revan Robes appear. It also adds models and textures to Darth Bandon for all other columns so he is no longer a broken character.
• Removed Darth Bandon from the broken character list.
• Removed "g_a_clothes04" from the Omit Items list. This was a previous attempt to fix this issue, which is no longer necessary given the current solution.
• Added clarifying info to Item Spoilers.

I just remembered that I didn't handle randomizing the appearance 2da. I will add changes to handle that soon.
