[Zope-Perl] Alpha 6

[Gisle Aas]

I hope it will eventually appear on <ftp://ftp.ActiveState.com/Zope-Perl/>,
but for now pick just it up from <http://gisle.aas.no/zope-perl-0.2.a6.tar.gz>

Changes since alpha 5 are:

   The default build flavour of "Perl for Python" is now MULTI_PERL.
   It means that each python thread get its own perl interpreter.
   This avoids the need for a perl lock and allow each the threads to run
   with full concurrency when inside perl.  The downside is that perl data
   can not be passed back to python in this mode.

   Adjusted Zope products to be compatible with MULTI_PERL.

   Added a README file for ZDBI_DA, mostly to explain the connection
   string format.

   Build patch (less hardcoding of perl/python paths)
   by Joseph Wayne Norton <norton@arseed.co.jp>

   Implemented perl.defined() function.

   Implemented Python::id() function.

   Made the PerlMethod icon look more dangerous :-)
