Also corrected many formatting errors in the comments in C and H files

This reverts commit 2e1e671d.

- normally only for doxygen generation, not needed in the path

- also update links from opencfd.co.uk -> openfoam.com

- makes it easier to copy Doxyfile for local Doxygen generation
  ie, for debugging and writing without processing everything

XiModel.H
SCOPELaminarFlameSpeed.H
basicXiSubXiEq.H
basicXiSubG.H
Doxyfile (include PATH to OpenCFD Macros)
doxyFilt (include class documentation in /src)

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"
)

  * output full file path
  * 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
