Support for multiple files of the same type in a FileSet
|Reported by:||Nicklas Nordborg||Owned by:||Nicklas Nordborg|
This is a sub-ticket to #1153. We expect that the model we need require that lots of files can be stored and related to an item in an organized way (eg. in a
FileSet). The current restriction that only allows one file for each file type is too limited.
This change is a big change that require backwards-incompatible API changes and database changes that require special handling when updgrading (eg. we must at least remove the unique constraint that restricts us to one file per file type).
