Post-build callback for entity browser elements.

This function injects the number of default values the entity browser has into its JavaScript settings so that several instances of an entity browser on a particular field can respect the field's cardinality. This is used by our special-sauce JavaScript in browser.js to ensure that you cannot select more entities than the cardinality will allow.
