Build data file for CombatHandler

[kikisaints]

Should have .xml file that stores all combat information that's loaded up into a data list for reference during gameplay (currently just pulls static data from a switch statement at runtime, this isn't good). This handler is for both monsters and the PC.

The data that should be in the .xml file is:

• Damage formula based on attack type, character stats, and weapon
• Subset string list of combat options based on weapon type being wielded
• Label for whether the attack type is a monster-only attack, player-only attack, or either

This .xml file should be called CombatData.xml and will be loaded and handled by the CombatHandler.cs file (which today has the hard-coded info).
