[X2Go-Dev] New help output system for X2Go Client

Hi,

The current x2goclient --help output has been bugging me for a while.

I have replaced the old output with a new, dynamic help output system that automatically formats the printed text based on the terminal width (for UNIX-based systems and on Windows.)

Besides automatic formatting, another design goal was to make it as easy as possible for other people, including non-coders, to add parameter documentation.

I hope http://code.x2go.org/gitweb?p=x2goclient.git;a=blob;f=src/help.cpp;h=718f18b... is holding that requirement.

N.B.: broker options have also been added.
