[Cdash] Configurable tracker URL

[Mathieu Malaterre]

Hi Julien,

  I have started using the secret BUG: regex for defining the bug. But
it seems this is somewhat hardcoded deep down in the code. Could there
be a way to have it user-defined. Eg:

http://www.cdash.org/CDash/viewChanges.php?project=GDCM&date=2009-11-20

  Points to http://sourceforge.net/tracker/view.php?id=2900591

while the correct URL should be:

http://sourceforge.net/tracker/?func=detail&group_id=137895&atid=739587&aid=2900591

Could you add a second URL for the bug tracker specifying the root URL
to use for this case.

Thanks
