Web Users List View B3 Updates

ALL UPDATES ARE IN A DUPLICATE VIEW

This view will be made visible under a feature flag once I complete the user list pagination functionality. Note that I am still working on that, but figured I'd get the bootstrap 3 updates out of the way before this PR gets any larger...gah.
