Greater browser support

Basically, get ads to work in IE8. Bulk of the work was moving away from using the cool native array functions, which don't exist, to lodash

Also, now using proper qwery, not the mobile variant

However, still doesn't work due to an [issue in reqwest](https://github.com/ded/reqwest/pull/152)
That's going to cause style regressions, an `is-modern` class would be great.
