Change "Crayon" header on toolbar button

[NL33]

When adding Crayon to the text editor, the button displays as "crayon". Is there a way to change this?

This is relevant for me because this is how the button appears on comments as well--so readers/users of the site would have to understand what "crayon" means. It would be easier if the button said "code" or something like that.

By the way, this plugin is truly helpful.
