[done] Please make some command line options not depend on SDL

[tomreyn]

While --headless-server-mode works fine without an X display, this doesn't work for most other options currently (r2576):

Code: [Select]

$ DISPLAY=:-1 ./dev_rungame --help
Couldn't initialize SDL: No available video device

Please make at least the most basic options, such as --help and --version, work without SDL. If possible, please also make the --validate-* options work this way.

[softcoder]

Done in svn rev#2583 (but could not do validation functions as they currently use video settings for loading images and models etc for validation)

- modified the following commands so they don't required SDL video mode:

Code: [Select]

--help
--version
--show-ini-settings
