By default a Button with ModalResult = mrNone will not close it's
parentform when clicked.
A TBitBtn with Kind = bkClose and ModalResult is the exception to this rule.
It should close the parentform, not setting it's ModalResult (which
will result in ModalResult of parentform being mrCancel).

A TBitBtn with ModalResult <> mrNone should always set parentform's
ModalResult (regardless of Kind), which is what my patch does.
