Moose::Meta::Attribute

• made the +attr syntax handle extending types with
  parameters. So "has '+foo' => (isa => 'ArrayRef[Int]')"
  now works if the original foo is an ArrayRef.
  
• added tests for this.
  
• delegation now works even if the attribute does not
  have a reader method using the get_read_method_ref
  method from Class::MOP::Attribute.
  
• added tests for this
  
• added docs for this
  

Moose::Util::TypeConstraints

• passing no "additional attribute info" to
  &find_or_create_type_constraint will no longer
  attempt to create an ANON type for you,
  instead it will just return undef.
  
• added docs for this
