Improvements to attacks.

• Added damage variance.
• Added crit chance and modifiers.
• Added projectile speed to character stats.
• Simplified the process by adding a Calculate() method to AttackStats that will handle all the work.
• Changed the code so not having a hp or xp bar won't cause exceptions.
