Feature/ci

Hõla,

I've polished my ci_engine a bit, It is now able to read the agents it is supposed to test from an ini-style config file. This way one can easyly check out different versions of the same bot into some directory and test.

Currently the engine is only runable as a command line script running in an infinite loop and providing updated results after each game. It produces output like this:

It is planned to extend it to a web service like thingy, but until now it is still very useful as it is.
