Demo deactivation and small update with bug fixes

Today I deactivated Birb game demo, because I don't think it is representative of current Birb Game. Demo will probably return later, but after I get to updating it to better represent the way Birb game's moving in. Sadly I'm not able to update both the full game and demo at the same time, because even if I try to, the day only has 24 hours.

On more positive note.

I've fixed some bugs, where the game could crash in multiplayer and after finishing a round, some players wouldn't get their deserved achievement nor would they see the winners screen.

Now I've been for some time working on few bigger update, for example update to the games rendering, so that it can run better on lower end hardware without a big hassle.
