Added front-end portion for registration

Added Registration form to application and link to reach it. This is
only the front end portion the backend has yet to be implemented.
Devise Added to Application

HI! BILLY MAYS HERE! TIRED OF HAVING TO REIMPLEMENT USER AUTHENTICATION
OVER AND OVER AGAIN IN YOUR APPS? WELL NOW YOU DON'T HAVE TO!
INTRODUCING DEVISE! IT DOES ALL THE STUFF FOR YOU LIKE SETTING UP VIEWS!
MIGRATIONS FOR YOUR USER TABLE! AND THE MODEL TO MATCH!
Login and Registration moved into navbar

Navbar now contains the link to Login and Registration.
Fixed typo of password in user model.

Password was misspelled causing issues. Fixed
Bootstrap form gem added

The forms from Devise do not fit in. Getting bootstrap styling for them
so they don't stand out too much.
Got User Registration to work!

User registration is done through devise. The view provided by Devise
has been modified to use bootstrap styling as well as provide two
additional fields.
