FR: Support additional rotation schemes such as SRS

[indiscipline]

This is certainly doable. The current look-up table for figure rotation can be made switchable.

However, full specs of SRS, for example, specify Wall Kicks. This is an additional game mechanic which I don't think is so important, especially considering the long legacy of it not being present in the original game at all.

So, waiting for user feedback on this one. Do you want just other rotation schemes for their own sake or do you want other mechanics such as t-spins and wall kicks which they bring?
