Let Lenya 1.2 users upgrade to Lenya 1.3 since complete
backwards-compatibility was a goal. Lenya 1.3 should be usable in a
few weeks.  The high-level feature list reads just like 2.0's What's
New.  The largest strategic difference is no Java in Modules, but that
cannot be a problem since 1.2 did not have that feature.  Just copy
Lenya 1.2 Publications to the pubs directory.  The implementations is
very different from Lenya 2, but a normal user will not care.  The new
features become available after a simple conversion to the new
datastore.  (Jorn will love that Areas have been removed.)

This frees Lenya 2 development to focus on new features for new installations.
