The {$interfaces corba} in every MSEgui unit is because a FPC bug.

It is fixed now, I will remove the no more needed {$interfaces corba} soon.

tnullinterfacedobject is needed in MSEgui for Delphi compatibility because
Delphi has no corba style interfaces.

use the function getcorbainterface from lib/common/kernel/mseclasses.pas.
