When using the 'Replay' cache mode the cache needs to be invalidated whenever simulation variables have been changed.
The invalidation will always only affect the according subcaches, e.g. when changing a mesh paramter only the mesh cache will be invalidated, the base cache will remain intact.
Before this change Blender always invalidated the entire cache.
A collection of smaller changes that are required in the /blender/source files. A lot of them are also due to variable renaming.
