[bug#34086] [PATCH] Add StepMania

[Nicolas Goaziou]

Hello,

This patch adds StepMania. 

Note that I had to remove all bundled songs due to a non-commercial
clause, so it's not really usable right out of the box. I also had to
package a dedicated FFmpeg package, since StepMania is very picky about
it.

Feedback welcome.

Regards,
