Overhaul how the Application object is initialized (replace long function with a somewhat structured recipe).� Include tests for initializer functionality.

Main and temporary databases are no longer configured by default if databases aren't provided in the configuration.  Change zope.conf.in to specify root and temporary databases.

Don't create "default" databases if none exist in config file.  At least one database (the root database) must be specified in zope.conf for Zope to start properly now.

Dont maintain a configuration separate from that of the global config by using a module-scope global.  This causes problems when the global config changes (the
changes are not picked up here).  This is typically an issue when running unit tests.

Add a dummy dbtab attribute on the DefaultConfiguration for machinery that expects this attribute to exist.

Support for ESMTP user+password authorization. Strange, the last commit didn't seems to stick... Trying again.

Dont try to set attributes on cfg in setConfiguration if we're trying to clear the configuration by passing it None.

- only sort the results once

Added getId() to Item_w__name__, since the one inherited from Item
has broken __name__ handling.

PageTemplateFile now using Item_w__name__ mixin, making getId()
and absolute_url() actually work.

When a VHM is activated, it adds the mapping 'VIRTUAL_URL_PARTS': (SERVER_URL, BASEPATH1, virtual_url_path) to the request's 'other' dictionary.  If BASEPATH1 is empty, it is omitted from the tuple.  The joined parts are also added under the key 'VIRTUAL_URL'.  Since the parts are evaluated before traversal continues, they will not reflect modifications to the path during traversal or by the addition of a default method such as 'index_html'.

Collector #1012: A carefully crafted compressed tree state could violate size limit.  Limit is no longer hardcoded.

This was the Python 2.1 support for RestrictedPython.

Collector #809: Added and documented Traversable.py methods absolute_url_path and virtual_url_path, and reverted earlier change to absolute_url behaviour.

- removed unused imports
