Disable animation support for Clearlooks by default.
Bump PKGREVISION.

Upstream says (http://bugzilla.gnome.org/show_bug.cgi?id=583278):

Our animation support is more a hack than something else, and I
would prefer to remove it rather than enabling it :)

Maybe in the future, Gtk+ will provide better API for animations,
and we could write a better approach, which uses less CPU cycles
for example.
