Experience

Experience are points that the player's Captains can gain during any battle except for training one.

This is how Captains gain experience at the Arena:
 * The 1st victory in 24 hours doubles experience points gained by the Captain
 * Victory, if the player survives
 * Victory, if the player does not survive
 * If the player loses battle
 * If the player destroys the enemy ship during Team Deathmatch
 * If the player destroys the Alien Boss
