devel/SOPE5: Add version 5.1.0

From pkg/55459 submitted by Dima Veselov, and followup via email, with
some modifications by me.

SOPE is an extensive set of frameworks which form a complete Web
application server environment. Besides the Apple WebObjects
compatible appserver extended with Zope concepts, it contains a large
set of reusable classes: XML processing (SAX, DOM, XML-RPC),
MIME/IMAP4 processing, LDAP connectivity, RDBMS connectivity, and
iCalendar parsing.
