System information

• SolveSpace version: 3.0~ bd41485
• Operating system: Debian 10 buster (MX Linux MX-19.3)

Expected behavior

solvespace and solvespace-cli should has an option to show version in terminal output:

$ solvespace-cli --version
3.0~{git_commit_id}
$ solvespace --version
3.0~{git_commit_id}

Additionally solvespace should has --help as next:

$ solvespace --help
This is SolveSpace 3.0~{git_commit_id}

Usage: solvespace [filename...]

To use SolveSpace in CLI mode see `solvespace-cli --help`

Actual behavior

1. solvespace-cli missed --version option;
2. solvespace missed --version and --help, instead it recognizes those option *as file names to open — as result it starts in GUI mode with error message window "Error: Couldn't read file from '--version'".
