Added general styling for sign in page and also implemented CSS fixes for bootstrap images.  Next up is sign up page and should be more of the same.
Further added navbar functionality including a search box that sends a get request.
The model search works in testing but will need controller input actually display the render.
Unsure if it returns a filtered index page or a seperate search results page at the moment.
Something to noodle one.
Merge pull request #3 from allcentury/styling_pt2
