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.

etc/controlDict: Set SolverPerformance debug switch default to 1

Also remove the "<thermo" part of the names of thermodynamics packages

To support these changes the need for "Sp" corrections on div-terms has been
eliminated by introducing a "bounded" convection scheme which subtracts the Sp
term from the selected scheme.  The equivalent will be needed for the ddt term.

A warning message is generated for steady-state solvers in which the "bounded"
scheme is not selected for the convection terms.

- Re-located mapped point patches
- Updated mapped patch write
- deprecated directMapped in favour of mapped
- updated resulting dependancies - apps/libs/tuts

- add doc-dir doc/doxygen so it doesn't get forgotten

Making sixDoFRigidBodyMotionConstraints less verbose by default, now
requires debug switch to be set.
