extend the user interface of of the "Download from Url" dialog with an
option to choose a decompression algorithm to decomppress the image
after download.
extended the query_url_metadata function to also automatically determine
if a decompression is needed. If it is it will be automatically set in
the UI

extend the download_url function with the capabillity to handle
compression
add decopressor info for images
build compression algorithm regex dynamically to avoid duplication
