MediaUpload fallback

[rafzielinski]

When uploading an image via MediaUploader it's not generating the crops bigger than the image original size (which makes sense) but it's not working correctly when it comes to calling for crops from the front-end.

If for example, we would upload an image with a resolution of 1150px x 900px when we call for :landscape_1200 crop we get nothing but fallback.svg back.

Expected behavior: serve a smaller version of the image if possible. ie:

• if for the example above the :landscape_1200 crop is not available, it should try to get you :landscape_1000 back
• if that is not available maybe it should search in different crops, like content_1200
