gui: Update about logo icon to denote chain type

Adding the networkStyle parameter to the HelpMessageDialog
creator on utilitydialog, updating all calls where its instance
is being created from bitcoingui.cpp. In the object itself,
use this new parameter object to build the about window title and
set the icon of the about logo widget.

Also, set th correct chain type icon at the very beginning of
GuiMain() where command line arguments were validated and most of
the app settings were not initialised yet.
