working #2

getting specs and gems setup correctly for dev/testing
working #1 bootstrap-sass

Downgraded to version 3.1.1.1 so that IDE can read the assets due to a change in 3.2 gem. http://youtrack.jetbrains.com/issue/RUBY-15585
working #2 - auth

minor update to user model and sorted out gem file.
working #2 - enhancing roles

adding the actual roles to be used for the application and updating the user model to have a first and last name, versus a complete name.
fixes #2 - roles and access

poorly ensures that top three roles have access to users via the UserPolicy. This will get cleaned up as I learn more about pundit.
