Remove jira group from Gemfile
Allow web app to be run with sqlite db
Authenticate as user when importing pull requests
Pass GITHUB_TOKEN as :password

Github allows a user's password to be the real password or an oauth

this commit switches the :password value. It's a bit cargo cult, but
this should be a more frequently travelled codepath.
Add documentation to github client validation
Merge branch 'local-dev'
