[aur-general] Merge request: sm-ssc-hg into stepmania-git

[Devin J. Pohly]

Please merge sm-ssc-hg [0] (orphaned) into stepmania-git [1].  StepMania
development has moved to GitHub, and the "sm-ssc" name is long outdated.

0: https://aur.archlinux.org/packages/sm-ssc-hg/
1: https://aur.archlinux.org/packages/stepmania-git/

Thanks,
