FS#112 - OpenEXR alpha is only written when it shouldn't be

OpenEXR output currently writes an alpha channel when Output_Alpha=off (-UA), and does not write an alpha channel when Output_Alpha=on (+UA), i.e. doing it just the wrong way round.

No feedback since two months, so presuming that no news is good news.

Fixed with change #4976.

Actually an alpha channel was always written, but forced to 1.0 (= fully opaque) when "+UA" was specified, and left at computed alpha when "-UA" was specified; changed this so that alpha channel is written properly when "+UA" is specified, and is physically omitted from the output file when "-UA" is specified.
