Restore Modals for speakers

[abelmartin]

This was a feature in the previous design. This should get restored.

@abelmartin we should get this done before the conference. Is there any blocker besides time?

[abelmartin]

So, one blocker is what will be in the modal? Before we had the bio & talk in there. Does that still make sense?

I think that 2017.goruco.com should be the model. Truncated talks on the main page to tighten up the speaker section and a modal with the full talk abstract and speaker bio.
