symmetryPlane: add symmetryPlane as a special type of symmetry condition applied to a single plane

The standard/previous general symmetry type is now named symmetry
    both in class and lookup name for consistency.  The rigorous
    symmetryPlane type is needed for moving-mesh cases in which the
    motion it constrained by one or two planes.
