update dependencies

[minnypatel]

I've used npm's automatic tool to update the dependencies to fixed versions. To test:

use git to checkout to this branch:

• in terminal navigate to the project directory
• checkout to this branch using git checkout dependencies-update
• run npm install to install the new dependencies
• startup the website locally as usual (I don't remember how but it should be in the README.md`
• run through the core functionality of the website as a user and make sure everything works
• if anything doesn't work, make a note of exactly what you were doing, and any output in the developer tools console.
• don't forget to git checkout master when you're done
