Documentation improvements (#859)

- print link to where documentation is generated
- remove old documentation css
- configure alabaster to display Github stars/Travis CI, and fork me badge
- allow the documentation to span up to 1280 pixels, instead of 800 (this allows many code examples to be much more readable, or changelog entries)
- remove large spaces in between changelog entries for a more compact view
- version strings are italic and bold for a cleaner delimitation inside the changelog
- sections in a version changelog has a smaller top margin for a more compact view
- automatically render news at top of the documentation under DRAFT section, this allows testing the news fragment before release
- remove double header for changelog 
- use the ``:user:`` extlinks for changelog entries to link to contributors
Github profile
- improve changelog entry for issue #858
- add a config file for readthedocs
