Fixing navbar after upgrading to sass-rails 4 and bootstrap-sass 3.2
More bootstrap.fun-bootstrap (band show page looks normal again, specifying html 5, navbar tweaks to try optimizing for window resizing)
Installing Devise, setting it up for bands (though may create as 'user' model and tie to bands and venues), adding login widget to header
Before filter for bands_controller, generating default devise views so I can customize them
