setup superuser with devise and rails_admin

I wanted to have a dedicated model to act as a site-wide administrator
because most users would not need this feature.
generate devise for employees
install foundation-rails
setup devise default views and employee routes

convert devise views to haml
setup cucumber and rspec
Employee updates basic information
Employee sees roster
fix dropdown non-responsiveness

Turbolinks has issues with Foundation, according to @ace-subido.
show a placeholder for employees' event calendar
use update instead of update_attributes
