Added several urls and did HTML work

I added HTML files; dryer, joel, range, refrigerator, staff, and washer. I also worked on the model appliance to improve the view on the webpage. I also added more static files, or images to be displayed on the staff page. To add the urls, i started with the test, then i wrote the view, template, url, and anything else i could think of, then i ran the test. I was adding urls and passing tests on the first try.
