Enlarge the sharing input so that the full URL can be seen.
In my class with MacOS X and Safari the sharing URL box wasn't
wide enough and the last characted was out of sight. Adding
10 pixels fixes the issue without braking the desing in any way.
Added buttons and janky print function
Added in correct URL detection for print source.
Draw Anna/Elsa circles more nicely by turning during same frame as forward movement.
Merge branch 'staging' of https://github.com/code-dot-org/code-dot-org into sharing-print-button
Added in more concise print function (hidden iframe) and changed a click handler to jQuery for IE compatibility.
