Battle System Improvements

So, I've made some improvements to the battle system, switching from something other than RPG Maker MV's default battle system to one that better reflects what I'd like this game to be. After running some tests, I think it's ready to work, but some bugs have probably slipped through the cracks, so if anyone finds anything I'd appreciate a report.

Changelog:

• Installed Instant Turn Battle System by DreamX, switching from "all commands selected at the beginning of the turn" to "commands selected before a character acts"
• Fixed bug where Arise spell would not revive characters as described
• Begun work on Chapter 5
