.zpaq, set .ZPAQ date to 01.01.1980 as a marker

Franco, RoboCopy create files with the date January 1, 1980, while copying. Once the copying is completed, it assigns the correct date. Do you think it’s a good idea for ZPAQFRANZ to do the same? This way, it would be clear which parts are likely unfinished.

This will slow down A LOT extracting a large amount of files, especially over a network, where latency is so high

Hello Franco. I had something else in mind; I didn't explain it well. When archiving, the .ZPAQ archive itself should have such a date until the archive is finalized.

It required quite a bit of editing, so I hope I didn't “break” anything. It is included in the 60.8k version just uploaded

Tested, it works ;)
