Styling2

Separated date and time input for new/edit appointments
> correct information is showed when editing versus when creating a new appointment


Adjusted `appointments_controller.rb` to accept new inputs for date and time
> removed dangerous `.permit!` in favor of individually permitting required hashes


Applied proper/consistent styling to all forms and made UX more standard

Gemfile now dictates `Ruby 2.1.1` to coincide with recent version on local machine

Cleaned up `application.css` removing `margin-**` and using `margin` instead

Greatly improved seed file's variety and amount of generated appointments/services
