Implement Persistent Creature Data

[buckly90]

Having persistant data for specific creatures is essential for many functions of the game, such as handling learned versus learnable versus active moves during a simulated battle. It is also essential for handling team composition during battle.

Battler data should save the following:

• Name
• Species
• Level
• Experince
• Learned Moves
• Active Moves
• Current Health Value
• Coloration (May potentially go unused.)
• Loyalty Value (May go unused.)
