Portal web services to declare existing skins and backgrounds
To have a better way to configure portal skins and backgrounds in Manager, I think we can have a simple REST service that will return list of skins and background, by scanning file on disk.
For skins, each skin could have a little screenshot image in its directory. For backgrounds, we can display directly the background image, like it is done today.
This will allow to create custom skins and backgrounds and configure them directly in Manager.
