Add a fortune.conkyrc and setting it on OB.

Adding fortune.conkyrc that just displays fortune and add it to
autostart.sh from openbox to start it with it.
Fixing bashrc new setting to work with linux term.

The previous add setting in bashrc to change the window title proved
me wrong in removing the conditional to apply it just to xterm*/rxvt*.
As turns out, the linux console terminal do not play well with this
stuff. So now we filter it by $TERM variable.
