Build: Install Doxygen docs and include in distribution if generated.

Added a install-data-local target to install the Doxygen documentation
only when it has been generated. In order to correctly remove the docs,
a corresponding uninstall-local target was added.

If the doxygen docs exist in the source tree, they will also be included
in the distribution now too.
