Сustom options.classes do not apply

[cap-Bernardito]

function Headroom(elem, options) { options = options || {}; Object.assign(this, Headroom.options, options); Object.assign(this.classes, Headroom.options.classes, options.classes); ...
this.classes == Headroom.options.classes(default options.classes), but not options.classes(custom options.classes);

Gah, don't know how I missed this. Will add some tests for this and fix later

Messed up the initial release, but this is now on npm as v0.10.2 :)
