Bower update

And downgrade qwery to 3.4.2 (4 doesn't support <= IE8)

Also removed its entry from `bower.json` so can't be updated accidentally
`resolutions` still in there (https://github.com/guardian/frontend/blob/bower-update/common/app/assets/javascripts/bower.json#L20), just made the new video libs `dependencies` rather than `devDependencies`
