Create a bot to play with while there are no online players

[sphynx]

The bot should play more or less randomly (+- 5/10 degrees from the optimal angle) to be interesting and non-invincible :)

There might be also different strategies for choosing target pieces.

The bot should be implemented on the client side to be able to play offline.

Create 2 bots: Anka (more powerful bot) and Pet'ka. Differ them visually from real gamers.
