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

- change from 'kde-open %f' to the desktop-agnostic 'firefox %f' as
  the default document browser.

- removed globalPointPatch*
- removed pointPatchInterpolate*
since all is now inside volPointInterpolation.

which need this functionality.  Solvers will now check the correctness of the BCs on
read.

- change name of environment variable from $WM_OS -> $WM_OSTYPE
  as a better description

- added obj surfaceWriter
- don't bother with prepended field names on obj and stl surfaceWriter.
  It fills the disk and suggests differences where there are none.

- put back debug switch (even although it is never used)
- remove stringsGlobals.C, since it is now never used

- string doesn't use any debug info, remove it
- restructured the macros to add in NoDebug macro versions to className,
  typeInfo.  Might be helpful with tackling the globals bootstrapping issue.
- HashTableName + StaticHashTableName - avoid lookup of debug switch when
  FULLDEBUG is not defined

This reverts commit 7446cee7.

 Added doc/Doxygen/tools/find-debugNames to help but the problem requires
 more attention (Henry/Andy/Mattijs?)
 Caveat:
   - names defined with nested defines will be missed.
   - names defined via typename will be missed.

Cleanup example:

#!/bin/sh
(
cd $WM_PROJECT_DIR
doc/Doxygen/tools/find-debugNames|tee debugs.orig|sed -e 's@ *//.*$@@'>debugs
diff -uw etc/controlDict debugs > debugs.diff
echo "hand-resolve the conflicts - see debugs.diff"
)

This is useful when the application has the same name as a class. For example,
polyDualMeshApp.C implements the polyDualMesh application using the
polyDualMesh class. Thus polyDualMeshApp_8C.html documents the app, whereas
polyDualMesh_8C.html is the annotated source code for the class itself.
