Products.ERP5Catalog: EPR5-ify catalog.

Move from SQLCatalog to ERP5Catalog as the default Catalog inside ERP5.
The major difference is use of Products.ERP5Type.Core.Folder as Catalog
base class.

Significant changes:
	-Inherit from Catalog class from Products.ZSQLCatalog.SQLCatalog instead of copy-pasting the whole code again.
	-Add allowed_types for ERP5Catalog tool
	-Monkey patch some property setters and getters to maintain consistency
	-Update id and title for ERP5Catlog while class initialization
	-Set declarative securities and solve some inheritance conflicts
	-Add isRADContent for ERP5Catalog Class
 	-Solve inheritence conflict for _setPropValue function in ERP5Catalog class
	-Add SQL Method portal_type in allowed_types for ERP5Catalog class
	-Override getCatalogMethodIds cause it uses global variable in SQLCatalog.Catalog
	-Redefine security declarations
	-Add functions for object_actions of Catalog portal_type in ERP5Catalog object
	-Add filter_dict and _properties attributes for compatibilty
