[gnome-latex: 48/205] Command line options: --version, --help, etc

[Sébastien Wilmet <swilmet src gnome org>]

commit 0cbcaefc26523f8ebb07f3cf4d975eb125109195
Author: Sébastien Wilmet <sebastien wilmet gmail com>

    Command line options: --version, --help, etc
    
    The version option print obviously the version of LaTeXila but also the
    versions of the libraries used (GTK+, GtkSourceView and GLib). To know
    the version of GtkSourceView, we use CMake and the config.h.cmake file.
