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"
)

  * some preliminary file edits to restore 80-col max.

Doxygen filter changes * allow doxygen to process applications/**.H * use @cond/@endcond to suppress documenting classes/variables in applications/

 - allows some access from applications to libraries
 - connection between application and local includes is still a bit weak,
   but is possible via the dirs.html navigation.

  * skip doxygen docs for local variables (treeBoundBox)
  * filter transforms 'Typedef' -> @typedef
  * added tools/find-retagged
  * manually changed some InClass tags to Typedef - still needs more attention
