[PATCH 4/5]: cleaning the template parent management in hgweb

From: Goffredo Baroncelli <[e-mail]>

Now the patch remove every use of the tag p1/p2/p1rev/p2rev from the
code ( even+the ones not used ), replacing everywhere with the tag
parent ( even where the previous +tag are not use ), so the
information to the templates is still given.
