field_cardinality

Set cardinality (max values) AND a required # values per field instance instead of per field everywhere.

For instance

• field_book in article has cardinality = 1
• field_book in thesis has cardinality = unlimited and required # values = 6
• field_book in user has cardinality = 2 and required # values = 2

This module requires a core patch. Details in #1029298: Allow cardinality to be restricted (overriden and reduced) in the field instance settings
