Implementing BDD User Sign Up/Registration (Routes, Controller, Views)

Same concept as Laracasts... different naming. Some divergence from lesson
- Adds Resource-ful `UsersController`
    - @create -> view `pages.register` <- *Keeping non-resourceful naming for views*
        - Basic form setup/styled
    - @store  -> temp `Redirect::route('home')`
- Updates routes/links to use named routes...
