Towards flexibility

[cmorty]

Here are a lot of changes I made to use this for a wedding. During the end I got bored making clean commits, but I still think the code is in better shape than at the beginning. And maybe someone can pull some ideas out of it. Changes include:

• Board looks more like the original
• Board can have an arbitrary number of fields
• Points can be arbitrary
• Unlimited number of players
• Lots of QLists instead of static arrays
• Code design was clean a bit.
  Regressions:
• Saving does not work (the format was so crude I was turned of fixing it)
• Although I closed some memory leaks I might have introduced new ones
• Never crashed in the final version, but well.... Might need some more testing
• Only tested with Windows. Not sure how the full screen stuff will behave on linux.
