* Use resource loader embedding for better performance
(uses a slightly hacky method to achieve this, the only
alternative would be to fix the WikiEditor API, but that
would introduce a version dependency)
* Use SVGs from OOUI where available or create new ones where not.
These are used and available under the OOjs UI MIT licence.
* Provide PNG fallbacks using LESS mixin
* Remove unused icons

Instead of running the jshint test through jenkins, Run it through npm
instead.
Also add composer.json for running php code sniffer and phplint instead of
running phplint through jenkins.
Also update grunt-jsonlint to 1.0.6
