Create Speakers repo for eventually-to-exist page of site

[hackygolucky]

As a speaker, I would love to share what I have spoken about previously and offer information on when/where I'm available to give this talk again.

As an organizer, I would love to have a pool of potential speakers to contact regarding speaking at my event.

Hoping this will be a page on the site.

The template and repo were being worked on by @chrisdickinson last we talked at Barebones. We'll sit on this a few days to make sure the initial push is in a comfortable place. We want it to be welcoming while not requiring so much effort as to reduce contribution.
