Add queue for print downloads and automatic cropping for saved prints (#1068)

Browse Source 
* Add queue for print downloads

To prevent issues with rate limits in instances with a lot of prints switch downloading prints to use a queue.

* Auto cropping for instance print saving

Add option to automatically crop prints saved using the "Save Instance Prints" feature and a popup to apply crop to all previously saved prints while preserving metadata.
