Bug Description

Object types are unable to accept ADD/REMOVE changers within structs, however specific types like number are.

Steps to Reproduce

struct B:
	value: object

on script load:
	add value() to {_a}

	set {_b} to B struct
	add value() to {_b}->value

function value() :: object:
	return 123

Errors or Screenshots

Line 8: (test.sk)
  field value of {_b} can't have anything added to it
  Line: add value() to {_b}->value

needs a special check in ExprFieldAccess#acceptChange() to see if the field is both single and Object, and always return Object.class
#change() should already support it
