Selectable Panel Images

• The feature let's you select old archived panel images from the rack view.
• Modules, which have archived panel images available have two arrows to select them.
• The default status of a module panel image is HEAD. That is the behavior everybody knows. If someone uploads a new panel image that will be the new HEAD. It will overwrite the old panel and be displayed in your rack.
• If you select an older panel with the arrow buttons this panel will be automatically locked for your rack and it will not be overwritten by future changes.
• The first panel you select is always the same than the HEAD, only that it is locked.

I did some changes to make the UI more compact so that it is possible to edit panels even for 1U modules.

Caveat:

• In many cases the different facepanels are not different at all, because users uploaded them again for technical or whatever reasons.
• If you upload a new panel image that will still overwrite everybody's HEAD.

TLDR; there are two arrow buttons to change the panels images.
