The readthedocs style for sphinx has an issue where it does not auto
wrap text in table cells. This results in very long cells with a
vertical scrollbar.
This adds a css style sheet to fix this wrapping issue.

This commit adds initial files for the Sphinx documentation system and
expanded checkcode.sh to include `doc8` as documentation checker. Also
added this checker to the dependencies for travis CI.
