Merge branch 'master' into dkurk
Made update.js correspond to the server side and update.html. The page preloads with the users' information based on their id, and allows you to change everything but the id. (It might be better to make the id field frozen somehow to prevent users from messing with it.) The only problem was that the route for deleteUser() wasn't made by helen so that needs to be done for it to be tested right.
