Adding term-colors.sh to show terminal colors.

This script from the interwebs show all 8/16 colors in foreground
and background and the defaults fg/bg in a matrix with all the
combinations. It is useful to see if the color palette is good to
be visible in all combinations, something that sometimes is a
problem, specially with programing and comments highlight.

- openbox/menu.xml
Adding dynamic 2-monitor support for initx.sh

We are adding this feature that was in OB "autostart.sh". In fact
I am adding single monitor support in "initx.sh" (the dual monitor
was hardcoded).
Also adding the old "delayinit.sh" from my old OB "autostart.sh"
as "ref" and adding some TODO for a possible
unification/integration in the two init styles I use across
different computers.
