78403: Merged EOL (5.0/Cloud) to HEAD-BUG-FIX (5.0/Cloud)
75700: ACE-2149: EOL AVM / WCM
- Remove most of the AVM and WCM beans, scripts, classes, patches, etc
- The Explorer client is very broken for compilation
- TODO: Remove all WCM-related functionality, which I thought would be best left to a UI dev
I've murdered many of the classes and beans but there's more to do
- The repository compiles
TODO: Get it running again
- TODO: Check if we can wipe the 'deployment' project as well
