add command-line options

[yeranya]

add command-line options, possibly in the style -o args / --option args

the current way command-line arguments are handled is not ideal, if specifying a port it must be the first argument, and dev mode is enabled by providing at minimum 2 arguments.

sidenote: dev mode is something that appears to increase verbosity of errors, disable downloading of the game mod, and disable game auto start functionality, these could be their own options

command-line options that could be possibly implemented are:

• -p PORT, --port PORT to specify a port to be used
• -v, --verbose to increase verbosity of errors and whatnot
• -g, --no-download to avoid downloading the game mod (-g: don't Get)
• -l, --no-launch to avoid launching the game (-l: don't Launch)
• -a ARGS, --beamng-args ARGS to specify arguments to be passed to the BeamNG launcher, possibly like -a '-gfx vk'?
• possibly another one equivalent to specifying -vgl similar to what dev mode was?
• in the event there's only one argument given and this could be a valid port number, maybe set it as the port to use, for backwards-compatibility reasons.

this software is made for windows, so windows style command-line options may be better? or maybe the style BeamNG (similar to Xorg) uses?

Acceptance Criteria

• -p PORT, --port PORT
• -v, --verbose
• -- to end launcher arguments, any arguments beyond are passed to the game
• --dev or the old 0 0 dev mode

In addition an option like [-L --Location] to print the current directory of the BeamMP-Launcher as well as the BeamNG userfolder location would be nice to have

The printing/logging of the beamng user folder was recently added and should be available in the next release
