Release of final Alpha version

Dear players,

now we have a final alpha version. Almost all the features I had in mind for this game are implemented, and I'm mighty proud of releasing this as my first (and maybe only) game. 

The bug concerning the curiosity box should be fixed.  Or more precisely, I think it is fixed, but I see that I not all curiosities might be displayed under wrong conditions, but I do not understand why because this bug only happens in html5.

I modified a possible pain point of html: let me know if you can read all curiosities. The last one concerns the expansion of the universe, so have fun!
