Fix: html links to File Reference pages

I have made a fix, maybe some one can verify this.

When SOURCE_BROWSER not configured, I now get a HTML link from the
'CTestExtra Class Reference' page, to the 'TestExtra.h File Reference'
page.

I have one minor problem... In my current project the 'local' flag is
not always set for local include files.
So var local == false.
The only problem I have is that the include is sometimes showed as
#include <test.h> in stead of #include "test.h"
But I think I noticed this problem earlier today also, before I
started hacking the code..
StdAfx.h works OK, but my TestExtra.h doesnt... Strange.
I have a really small test project, in case some one has any idea.

Below my changes, to get some working HTML Links..

Regards,
Edgar
