Merge pull request #72 from wesbos/master

fixing popup messages with trusted HTML
Fixes #71

We are now able to do pull requests. I had to rework how to set things
like username and password, but we should be good now.
Fixes #69

We're using the name and email from github now. If they don't have name
and email then we'll probably get the openshift user, but that would be
a pretty simple fix to have the user make. We could also change the
auther in the pull request.
Adding more docs about getting started

Pete wanted more than was there, or maybe he didn't fully read the
README. At any rate there is more information about getting started and
running the application.
Update README.adoc

Switched the git repo to the preferred repo URL.
Fixes #87

The site show now allow for multiple users. Repos are now separated via
username. I'm wondering if we should allow for multiple repositories
while we're at it.
