Patch from Jian Tao to add some callback functionality to the

warning system.  This allows thorns to register functions which
will be called when CCTK_Warn or CCTK_Info are called, with the
contents of the warning/info message, thus allowing thorns to
do things like logging warnings to file or displaying on webpages.
