Use setuptools directly

The current versions of commando and fswrap have been updated to use
setuptools. This change updates these dependencies to remove the usage
of distribute all the way down.

Distribute is deprecated; setuptools is now the recommended
packaging library.

Fixes #253, fixes #286

Revert "Dedupe deps"

We probably don't want an editable install normally, but we will for
development.

* Conform to changes from the newest Hyde version.
* Clean up Markdown and add explanations.
* Increase font sizes.
* Remove HTML5 shiv and hgroup element (deprecated).
* Other minor improvements.

*   Bugfix: Fix smartypants to 1.7.x to avoid the breaking
    changes in 1.8.  (Issue #229)
*   Bugfix: Upgrade Jinja to 2.7.1 - this fixes
    mitsuhiko/jinja2#243.

-   BREAKING:  While this change will correct the weird encoding
    behavior, this also changes the way `xxx_url` macros work.
-   Do not encode the url bases (`base_url`, `media_url`). Only
    the path component needs to be encoded.

-   Ensure that subfolders for `layout_root`, `content_root`,
        `media_root` and `deploy_root` works reliably
        on windows. Use `fully_expanded_path` for all path components.

- Also, fixed `raise_exceptions` commandline parameter handling.

*   Better exception handling. (Issue #204)
    -   Hyde now propagates exceptions
    -   Hyde does not raise exceptions by default. `-x` flag is required
        for raising exceptions on error.
    -   Traceback is available in the `verbose` mode
*   Upgraded to commando 0.3.4
*   Upgraded to Jinja 2.7
