Single user column type

[adrinr]

Description

Adding a new column type for single users. These new columns will return the data as an object, instead of the existing bb-reference that returns an array, allowing better validation and cleaner bindings.
No existing data will be migrated, the old columns will still return objects and it will keep the constraints validations (allowing multiple or single when required)

With this change, we will have the following strategy:

1. The bb_reference will be a type that will store an array of internal IDs
2. The bb_reference_single will be a type that will store a single internal ID
3. Both column types will have a subtype. For the time being only user subtype is allowed, but technically it can support any internal reference such as apps, groups, tables... The subtype will define:
   i. Input validation: are the IDs valid for that object?
   ii. Output enhancement: what other data needs to be populated when enhancing the id

Thanks for looking at this - it was a real mess and was spamming API calls.
