Adding a section about the slice filter

This code example shows how to loop over a subset of values in order to implement one common use-case of "break" in PHP. I decided to use the "full" notation of slice rather than the sugared version (that example would just be "for user in users[:10]")

Fix filename for batch filter documentation

The documentation on the website for the batch filter currently 404s See: http://twig.sensiolabs.org/doc/filters/batch.html

I believe this is because the filename is incorrect. This PR fixes that.

Minor typo in sort filter documentation

I've found this small typo while working on shuffle filter documentation in https://github.com/fabpot/Twig/pull/1038

I decided to create separate PR in case https://github.com/fabpot/Twig/pull/1038 got rejected

Best regards!
