iCE 0.2 is about to be released

I think it is now time to release the 2nd version of my chess engine. All the changes I did in the last 6 month should summarize into a nice improvement compared with iCE 0.1

last thing I activated is the permanent brain feature. I designed the engine from the beginning for it but did not enable it because of the more difficult protocol handshake and it makes testing more difficult. But as most other engines use a permanent brain (means they think also when its the opponents turn) I like to level the ground.

A final private tournament should give me the confidence that the engine is stable and it is really an improvement. I paired it against the same set of opponents that I paired its first version with and it did pretty good. Only Ruffian is still giving it a hard time.
