splitMeshRegions: Improved region naming
Changed the default region name from "domain" to "region" for consistency with the rest of OpenFOAM. Changed the multiple default region numbering to start from 1 rather than 0 because the top-level mesh in the case directory is always named "region0". Changed the default region numbering to only relate to the default named regions and does not increment for explicitly named regions. This avoids a naming dependency on the default and named region order. Added new option "-defaultRegionName <name>" to specify the base name of the unspecified regions, defaults to "region"
