Moved file path handling to regIOobject and made it type specific so now every object can have its own rules. Examples: - faceZones are now processor local (and don't search up anymore) - timeStampMaster is now no longer hardcoded inside IOdictionary (e.g. uniformDimensionedFields support it as well) - the distributedTriSurfaceMesh is properly processor-local; no need for fileModificationChecking manipulation.
