FileListEntryModel now contain image URLs for each image

[kevinruder]

An image URL is created for each uploaded image, these can be used as sources in image tags allowing them to instantly be used without processing. The FileListEntryModel is expanded to include URL.

Thanks for the suggestion!

Unfortunately this would cause performance issues, since the data URLs can be arbitrarily large. The intention is that any large blocks of data are not sent eagerly as part of the initial JSON block, but rather are available as streams for the .NET code to consume.

Instead of implementing it this way, please consider adding a .NET method to FileListEntry called something like ToDataUrlAsync that returns a Task<string>. That way, developers only call it if they really want the data URI, and don't pay the perf cost otherwise.
