Merge remote-tracking branch 'origin/v3.001-dev' into v3.002-dev

* origin/v3.001-dev:
  Disables TradeSignalManager.test.cpp test due to errors
  Generic ArraySize() now takes reference to constant.
  Trade: Improves performance issues
  Order: Adds missing order filling (fixes GH-664)
  Should fix problem "'array' - constant variable cannot be passed as reference" in Array.mqh.
  Made Dict and DictObject to have public Serialize() and SerializeStub() methods.
