A new Nikola's theme for my site: Zen

Some days ago, Aru Sahni wrote to Nikola's forum and posted a link to his site... I really like the theme he was using so I though to take it as a starting point to develop my own theme.

I had to re-wrote some things to accommodate the templates to the last Nikola v6.0.0 release (in fact, I usually use master from Github, but I recommend you to use the released code for production), and to make the theme more generic one and easy to re-use by others.

I got a clean and (I think) easy to read theme, with awesome icons (Font-awesome's if you didn't recognize yet), supporting both desktops/laptops and mobile devices and... I like it very much ;-)

It was a great exercise to learn more about html, js, css and less (a very interesting approach to deal with css).

I will publish the generic zen theme and the zen-ipython theme (which I'm using and you are seeing... right now) at the Nikola theme repository in a few days, after some more testing and customization.

Thanks again Aru Sahni, you are in some way the trigger for this theme... and very fun hours I experienced developing and learning by doing.

Damián.

PS: If you have any to say about the overall design, ideas for improvements, things you hate about this theme, just let me know in the comments. Thanks.
