Allow faking of options the engine fails to announce

A file DefectiveEngineOptions.ini will be read as if it is engine output
before any real engine output. This can be used to fake UCI 'option' commands
that the engine fails to announce, so that they will appear in the GUI's
Engine Settings dialog, and can be changed by user or GUI.
