Add language type attribute to programlisting tag

The current programlisting tag doesn't have any attribute to indicate
the code's language. This makes code highlighting customization
difficult.

For example, the current doxygen generated document doesn't hightlight
javascript code block. If one wants to customize the code block by
parsing the xml files and uses 3rd party syntax highlighter, there is
no way to tell from the xml file what language the code snippet is
using.

This change introduces an attribute "lang" to the programlisting tag.
