Move updates

[VictorABoye]

• Accuracy moves
• Critical hits
• Stat-changing moves (Accuracy, Attack, Defence, Crit chance)

Maybe for later:

• Status effects
• Weather conditions

Most things take place in:

• Changes to damage: https://github.com/AlexanderNorup/Modulemon-Advanced-AI/blob/master/src/main/java/dk/sdu/mmmi/modulemon/Monster/BattleMonsterProcessor.java
• Add new moves in moves.json: https://github.com/AlexanderNorup/Modulemon-Advanced-AI/blob/master/src/main/resources/json/moves.json
• Add support for new fields in the JSON here: https://github.com/AlexanderNorup/Modulemon-Advanced-AI/blob/master/src/main/java/dk/sdu/mmmi/modulemon/Monster/MonsterParser.java

Maybe start with just accuracy and critical hits.

Move on to stat-changes. Make sure you don't actually change the stats of the monsters directly, but add some kind of state to the stats (so it's per monster instance and can be easily reset)
