Add option to disable the toolbar.
This MR mainly adds the --disable-menubar
option, used to disable the toolbar.
It also cleans up a bit of code, adds the --version
and --help
options and changes the command line parser to actually show all processed options correctly in debug mode. The main reason to have --version
is to allow other tools to figure out X2Go KDrive Client's version if needed (although it will ignore unknown arguments anyway, so it is backwards-compatible to a degree).
