Title: NEW Add downsampling_only Image config

Prevent small images to be enlarged via `setHeight()` or `setWidth()` which in most case is a better solution.

This would save quite a bit of space on the server and also avoid creating larger images with lesser quality anyway, especially with responsive images approaches.
