Create a presentations page

[mojavelinux]

We are constantly asked about Arquillian slidedecks. This problem is best solved by creating a page that just lists everything we have. Likely this should get merged with the videos page to be something like "presentations".

yea, been thinking of a 'slidedeck.com' integration.

When we get the 'message->layout' separation up and running as well, it should be posted here.

Information from conversation with @mojavelinux

For the slides and videos page on the website, I'm thinking of something like this: http://www.ted.com/

A similar idea: https://plus.google.com/photos/fromcircles

This should be possible using bootstrap widgets w/o too much effort. I'm not ready to prototype it yet, just tossing the idea out there.
