Stable release 2.2.0

This brings full Contao 4.9 support.

Additionally there have been performance improvements
and various bugfixes.

- With the new interface ITranslatedMetaModel it is now possible to use a translated alias for the settings of the attribute at Alias - until now this had to be an attribute with "unique" values
- with change to interface ITranslatedMetaModel API expects at method widgetToValue the data value which was selected at attribute at alias - so far fixed to id
- widget as readonly now works correctly in the input mask; also in the popup picker
- a filter activated in the attribute settings now also affects the output in the VU - e.g. referenced items are no longer output if a filter limits this analogously to the display in the BE
