[Ideas] Allow computed columns within Database model

Computed columns are fairly standard across databases yet it seems like the only way to replicate that functionality with OutSystems is to create an Aggregate and add computed columns from there.

This would not be a terribly high priority issue since there is a workaround but support for computed columns within the model would allow for computed fields to be directly accessible from the data model without the need for an Aggregate sitting on top of it.

Ideally this would work for both simple computed columns and for those referencing scalar database functions.
