Changed so that Player is an abstract class instead of an interface and created the AI class.
Merge branch 'master' of github.com:marsj725/TDDD49 into AI

Conflicts:
	Player.cs
Updated so that the sqlite file is ignored by git.
Made a simple AI which first chooses a draw where an opponent is killed and if it can't kill the opponent it chooses a random draw.
Changed the gitignore to ignore orig files.
