Add patch-package and temp fix for passport.js 0.6.0 bug

patch-package allows seamless patching of npm modules (dependencies) without having to fork them.  You can modify the files in node_modules and use patch-package to capture the changes and reapply them each time the module is installed.
passport.js 0.6.0 currently has a bug that breaks the logout function.  The maintainer hasn't had bandwidth to fix it, but there is a pull request in github that addresses the issue.  The patch here applies the changes from the pull request to 0.6.0.
