setImmediate is broken in IE10 / IE11.

[wmill]

Calls to setImmediate won't working in IE10 or IE11.

Known bug since 2014, YuzuJS/setImmediate#35

Basically those versions of IE don't allow you to make a naked call to setImmediate, it must be called as window.setImmediate. However the setImmediate package doesn't install if there's a global setImmediate.

Workaround is found here, reflux/refluxjs#374

Briefly just set var setImmediate = window.setImmediate.bind(window); if there's a global.setImmediate.

I know it's really a bug in a separate package, but it's been open since 2014. I'm hoping you have higher standards and will implement the workaround :)
