Styling1

Added necessary minimum stylistic effects to forms and general web-app layout

Improved Devise generated forms
>placeholder text

Created desired format for DateTime displays
>appointment text messages and client views

Included a collapsable navigation bar in which alerts appear

Attempted fix for unappealing datetime_selector
>May want to work around by dividing up input to individual selectors and having the model/controller deal with the differences and create the DateTime.new object before saving to the model
>>Need validations!!!

Expanded seed file to generate 15 dummy appointments for the one demonstration client
>logical checks to make sure no appointment has the same service 2x
>>all appointments have 1 or 2 services
