It looks like some browsers may not automatically resize the editor button. I checked the Canvas editor toolbar and the icons are being set to 16x16 in CSS, so this PR changes the icon's native size to match.
To test this change:
[ ] In IE 9 or 10, open an instance of Canvas that has this plugin added.
[ ] Find a course you are an instructor for
[ ] Try to add a new assignment
[ ] The interface should look normal - no giant icon
