Release 0.91

The game is mostly finished. 

I've put basically everything I want in, maybe just the "connected" tag thingie is missing, and more examples in the second part of the book.

Now it's time to test the game and discover what I have to take away, make simpler and clean-up.

As promised, a little chapter on GMless and diceless gaming will be added later on.

I'm having a little trouble with the bookmarks, but hope to have this fixed once I release version 1.0
