An update to improve the game's AI and overall flow:

- improved the AI
- reduced camp to 1, with added nearby towers
- added a new victory condition: getting 10 hero kills wins you the game

This new AI should be more new-player friendly this time. And by reducing the number of camps to 1 the flow of the game is a lot better. With only summoning 1 hero per turn players can take their time on how to approach the enemy. 

And added a new hero, Yukino:
She can deal area damage from afar and can silence enemy spellcasters.
