Changes to image storage

Right now, has all images in a static upload folder. This means you can’t use some of the power of Hugo associated with Page Bundles, like the functions here Image Processing | Hugo.

It would be nice to be able to choose to use page bundles as an organizational structure.

This might be possible later. Some of the performance improvements we made this year could get us a little closer to allowing access to resources when a page is run through Hugo. Need to think about that a little bit more.
