Missing and invalid warnings on referenced files
The file list module in the backend offers the possibility to delete files. An interesting use case is the deletion of files that still have references to other entities. However, currently proper warnings are only available for sys_file reference.
a) before deleting a file, a popup should be shown
this does not work since the API is called with the identifier instead of a proper UID value
b) after calling the API for deleting a file, references should be pointed out
references are checked, however the description on the file usage is missing due to hardcoded "sys_file_reference" triggers - thus, no other references are printed out
