plegall 524011bfa6 Bug fixed: as rvelices notified me by email, my header replacement script was
bugged (r2297 was repeating new and old header).

By the way, I've also removed the replacement keywords. We were using them
because it was a common usage with CVS but it is advised not to use them with
Subversion. Personnaly, it is a problem when I search differences between 2
Piwigo installations outside Subversion.
