    Use requirejs for module loading

    spicyj authored
    Summary: Also did some misc cleanup in khan-exercise.js, mostly related to module-y things ("151 ++----"). I combined local jquery-ui into one file to make it easier to load.
    
    Test Plan:
    Opened addition_1, deriviative_intuition, graphing_points_2 locally, and all looked fine.
    
    In webapp/khan-exercises/, ran:
    
    ```
    npm install -g requirejs
    r.js -o requirejs.config.js
    ```
    
    then saw that /exercises/addition_1 looked right.
