Bugs, bugs, bugs...

When you are a solo coder and enter a contest, the problem with deadline is that you always consider it as the deadline for your compilation, not for the Q&A.

So, there were a few bugs discovered in Asteroids Chasers release, thanks to Kevin Mosley. 

There are probably some others, but this version remove the most annoying ones :

- Shuffling the cards : a last minute modification in shuffling leads to less balances games. Get back to previous version (still not perfect but better)

- Achievements : 2 succes were correctly trapped but not unlocked. Correction. This was the "21 mines..." and the secret "The big thing". 
If you already deactivate more than 21 mines, contact me, I will send you a patched version that will unlock the achievemtn next time you deactivate a mine. The reward should be nice : it is a mini-map (even if right now, it is useless and unreadable...)

- Undo was broken. It was nice to put an Undo option but side effect was worse than not using it. Undo is now working as expected (at least I hope). Remebmer, Undo is locked and you need to unlock it (tip : it is the "Need some help ?" achievement)
