Title: BAC-734 Image Serving results caching

* cache up to 20 images for each article, ``ImageServing::getImages`` will then take an appropriate slice of them
* mark ``ImageServing::getThumbnails`` as deprecated
* use JSON format by default when calling ImageServing controller via wikia.php
* a bit of code cleanup
