Fix Another ES5 Incompatibility in ControlBar.js
requested to merge github/fork/chrishalebarnes/fix-controlbar-es5-incompatibility-2 into development
Created by: chrishalebarnes
Fixed an ES5 incompatibility where a template string was used. Since ControlBar.js is an external module and is not compiled it should remain compatible with ES5.
Side note: ES6 will break uglifyjs since it expects ES5, there is a separate project uglify-es that has the ability to minify ES6.
