Coderefs: Add a java script constant to HTML exported buffers 

This patch adds a new constant with javascript functions.  Each
exported HTML file will contain these definitions.  Also, we add to
the default export CSS style a new class, code-highlighted, which will
be used to highlight lines in code whenever the mouse overs over a
link to this line.
