Redmine

The key/value-pair custom field type is currently limited to the same customisable contents as User and Version custom fields. For the key/value-pair custom field type this limitation is not necessary as the key/value-pairs are not project dependant.

The following patch removes the limitation inherited from the RecordList in the EnumerationFormat.

Another possibility would be to move the limitation from the parent class RecordList to the child classes that need it (UserFormat, VersionFormat), but that would mean that other existing subclasses (e.g. from plugins) would need to be updated if they rely on this limitation.
