#1016 Command line version info exists with non zero

[Hjalmar Joonas Valkoviiksi]

It seems that the exit code for the version information in the command line interface exists with a non zero code, hence gives the impression that something is broken.

Used command:

mediainfo --Version

Expected behaviour:

Show version details and exit with 0.

Current behaviour:

Shows version details and exists with 255 or -1, depending of OS.

Tested with version 0.7.88 in Windows, exit code -1
https://ci.appveyor.com/project/paazmaya/image-flatify/branch/master/job/83wvnhicnvi4dsn5
and 0.7.52 in Ubuntu, exit code 255

and
if (Return==MI_STOP)
return MI_OK; //no more tasks to do
