Updated readme

Added an acknowledgements section to the readme.
Implemented file conversion.

Markdown files are now converted in place into html files.
Added building to a different directory.

Now the built documentation is saved to the 'build' directory by default,
the user has the ability to override this via the --output cli option.
Fixed issue with the version command.

The version command was previously displaying the version information for
Glint, it is now displaying the correct version information.
Rendering with templates.

Implemented the base rendering of the content documentation content being
rendered into a mako template.
Adding assets.

Commiting the assets that are used by codify when rendering documentation
which I forgot to add on the last commit.
Added syntax highlighting.

The rendered docs now contain syntax highlighting. Highlighting is done
using pygments. The oppurtunity was also taken to tidy up the core
stylesheet to remove all the unneeded styles.
Updating code styling

Updated the code styling so that inline code will look similar to the code
blocks.
