Important: #82328 - EXT:form - use own folder for form definitions

See forge#82328


Change default filemount for form definitions to fileadmin/form_definitions, the directory is automatically created if necessary.

Existing forms in fileadmin/user_upload can be listed, duplicated and removed but not edited.

Since no migration wizard can be provided for this, a manual migration is necessary which can be done

  • by moving all form definitions to the new directory via filesystem or
  • by duplicating all form definitions (thus storing them in the new location) and removing the old form definitions.
