UI: New options layout for IO Add-ons

Updates importers/exporters for the new file-browser design. They are
now reorganized into sub-panels.

Updated the Blender version requirement (won't be compatible with older
Blender versions). Left the Add-on versions untouched, will leave that
up to Authors to change.
