#1654 Enable logging from commandline

[Kimmo Varis]

Made this patch months ago for my own purposes. I
didn't see general use for this then so I didn't submit
it. But now reading some other items this may be useful.

Note that I just merged my old patch and commandline
params handling codes seems to be changing lately so I
don't know if this even works. And no time to test. So
apply with your own risk..
