Add missing keyboard shortcut Shift + Ctrl + Alt + F to x2goclient 
documentation.

I spent an hour trying to figure why my X2Go session would not want to
go fullscreen over all my screens like I normally do.

I realized I always used Ctrl + Alt + F to go fullscreen as explained at
https://wiki.x2go.org/doku.php/doc:usage:x2goclient. That gave me 
fullscreen
session spanning over all multi display screens as expected.

However, without noticing it, I started using Shift + Ctrl + Alt + F
this morning because my muscle memory have been trained while using
Guacamole menu shortcut (uses Shift-Ctrl-Alt keys to toggle menu).

I did not notice at first, because Shift + Ctrl + Alt + F also works on
X2Go Client, but it only go fullscreen on current display screen.

It puzzled me for a while today, so I went back to wiki page, to figure
I have been using wrong shortcut.

I verified code for key bindings 
(https://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=etc/keystrokes.cfg;hb=HEAD) 

and it effectively offers two clever options to go full screen on multi
displays.

> 4 <keystroke action="switch_all_screens" Control="1" AltMeta="1" 
key="f" />
> 5 <keystroke action="fullscreen" Control="1" Shift="1" AltMeta="1" 
key="f" />

Here is two wiki patches to help clarify documentation around full 
screen usage
on multi display setups. Feel free to rephrase any way you want.
