In preparation to next version update, cleanup things a bit first:
- Add missing option description to "clients and servers" multichoice
- Sort the knobs in a more logical order within the Makefile
- Use more specific "gl" in USE_GL instead of umbrella "yes"
- Unbreak the build against Clang and clean up Makefile while here
- Transfer maintainership to the games@ team
