Register FlexJSON's DateObjectFactory depending on @DateTimeFormat on entities

Steps:

• Create a jpa entity with a java.util.Date field and use @DateTimeFormat (whatever)

• use json all to generate Entity_Roo_Json.aj

• trying to deserialize a date with iso-8601 format (like javascrip's, yyyy-MM-ddThh:mm:ss) gets an error, forcing to rewrite the two deserialize methods for each entity

whatever was tried with style="M-", pattern="yyyy-MM-ddThh:mm:ss" and iso = ISO.DATE_TIME. This issue could be solved by customizing FlexJson's deserializer in the Entity_Roo_Json.aj using a flexjson.factories.DateObjectFactory with the list of patterns used by the entity's date fields
