[svn-r25020] Description:

- Fixed a few comments that Doxygen gave warnings on.
    - Removed stylesheet from configuration so Doxygen will use the default
        stylesheet and removed the CLANG-related lines to eliminate another
        error since we're not using that feature, so the lines should not
        present. (from cpp_doc_config)
Platforms tested:
    Linux/32 2.6 (jam) - only changing comments
