add links to github, cpan, and irc to site

The website should have links to all the resources easily available. We
should put some big buttons in the body of the main page though, too.

Fixes #156
build the site when daemon starts up

Too many times I wanted to see my site with the daemon, only to forget
to run the build first. No more!

The build store is a temporary area that will be rebuilt all the time to
reflect the current state of the site.

Fixes #155
clarify what each destination Store is used for

The build store is the working area. The deploy store is production.
