order of "--save-pts" and "--nopreview" flags in veye_raspivid

[turbel]

This command (--no-preview before --save-pts):
./veye_raspivid --verbose --settings --timeout 2000 --output ~/Videos/testvid1.h264 --nopreview --save-pts > ~/Videos/testvid1.log 2>&1

yields the expected video recording and no preview on screen. Logfile:

However, this command (--save-pts before --nopreview):
./veye_raspivid --verbose --settings --timeout 2000 --output ~/Videos/testvid2.h264 --save-pts --nopreview > ~/Videos/testvid2.log 2>&1

generates the appropriate video, but ignores the --nopreview flag, as can be seen from the log file:
