Subject: qdoc: Added support for different source and output character
 encodings.

Previously, qdoc assumed Latin1 (ISO-8859-1) for source code and other
documentation, and wrote out XHTML with the same encoding. This change
adds additional configuration options (sourceencoding, outputencoding,
naturallanguage) that enable translated documentation in non-Latin1
encodings to be built with qdoc.

To be reviewed before merge into the master branch.
