Updated: mplayer now display correctly the picture

The problem with -geometry is it seems to have a different behavior
depending on the build, the -vo used or maybe something else...

Therefore I prefer to used -vf dsize= which will resize at most at the
size given and keep aspect. Plus -vf expand= to draw a black border all
around.

The black border is useful to hide windows below the movie but also to
expand the drawing area of the subtitles. Could be very useful!
Updated: run the starting script in background

It seems my dwm-session script and the dwm process itself receive
sometimes (for some reason I don't understand) a STOP signal and freeze
my commands...

It looks related to the connectivity because as soon as I disconnect the
cable, the processes get stopped. But I'm not sure and I didn't really
investigate.

It looks better with this modification.
Added: unmodified dwm

The only reason I used a modified version was to get the MOD+Tab
shortcut to go back to the last desktop. Since this feature has been
implemented in standard dwm, I just follow the main stream.
Fixed: closing STDOUT and STDERR with fish seems to be a bad idea

When I run gajim with >&- ^&- &, the accounts doesn't connect
automatically. But if I redirect them to a file, it works fine. So I
decided to redirect to /dev/null. This behavior is very weird but in
fact: closing an fd and redirecting it to /dev/null are two different
things.
