Until now, the TinselV* defines were used for discerning between
engine versions. The define TinselV2 was true for both v2 and v3.
Sticking to the old scheme would lead to confusion when more
special paths for v3 are implemented.
Renamed rince.* files to movers to be more game independent.
Added elementary support for Noir movers which can use different logic.
Allows game to boot to the first interactive scene, but there is no 3D model rendered (that is WIP).
