Updated all doxyfiles under doc/Doxyfiles. They are now all processed
by cmake but make targets are only generated for
OpenSceneGraphReferenceDocs and OpenThreadsReferenceDocs. The others
can be run with doxygen directly in <builddir>/doc.
Fixed a copy-paste in openthreads sproc and pthreads CMakeLists
Added the osg logo to the html footers
Added possibility to get generation of chm files.
CMakeLists (toplevel):
Added install of osg and ot reference docs. This also generates
packaging targets of openscenegraph-doc and openthreads-doc if you
have packaging enabled
Removed the unused USING_OP_OT_TRIPLE_SET since there was no way of
enabling it anyway
Removed BUILD_REF_DOCS. IMO it was redundant - BUILD_DOCUMENTATION
does the same thing and we get that anyway from including
Documentation.cmake.
OsgCPack.cmake:
Removed generation of PACKAGE_SRC for msvc
Added special handling for -doc packaging targets - they don't require
system, architecture or compiler"
