Address Firefox table-rendering issues in docs. Refactor to use colspan to provide table cells which can vary in width and indentation; the outermost has the greatest colspan, and each nested key has a colspan of one less than the parent, with padding cells for indentation.
Apply styling to table cells to get the table height to work without hacks or browser-specific
styling. Simplify the markup and CSS by removing extra divs. Use two passes over the options, return values, and return facts in the Jinja2 module-docs template: one to determine the maximum nesting depth to compute the maximum colspan needed, plus one to lay out the rows.
* Docs refactor as outlined in https://github.com/ansible/proposals/issues/79. Moves content into 'guides'; refactors TOC; fixes CSS; design tweaks to layout and CSS; fixes generated plugin, CLI and module docs to fix links accodingly; more.
* Adding extra blank line for shippable
