Title: Added script to remove unnecessary chunks from ExMaple 

I wrote a small Python script which uses pymclevel to remove the unnecessary chunks from the ExMaple.
That seems to work quite well although one still has to manually remove occuring lava/water from other chunks ([example](http://i.imgur.com/6qsnMIG.png)).

And I fixed the file permissions of the readme.md (removed executable bit).
