- Added OrderSupport and OrderedFolder.
- Added optional 'id' argument to Folder constructor.
- Modified main.dtml to play well with Folder and OrderedFolder.

contains a version name. If it does, then we check whether the user
globally has permission to join/leave versions. If they don't, we
clear cookie and raise Unauthorized. This will abort any changes that
might have been made during traversal. (If some traversal code makes
changes and commits them, then we still lose and probably deserve to.)

     - Collector #937: UnicodeError exception available within PythonScripts

With current CVS, the test runner reports:
Ran 2135 tests in 569.700s

OK

Add 2.3b1, 2.2.2 as acceptable targets.
Strip trailing '+' from version number in Python.

The Zope security policy now raises Unauthorized for all denied
access.  This is designed to make it easier to diagnose problems in
security settings, since the Unauthorized error will propagate to
something that can display or log the error.

All 2000+ of the Zope unit tests pass with this change, but I suspect
there may be code that expects the security policy to return 0 instead
of raising Unauthorized.  If any severe issues surface, we can revert
this change.

In Python 2.2 and above, getattr operations distinguish
AttributeErrors from other kinds of operations.  But Wrapper_acquire
was masking some errors as AttributeErrors.  Fixed.

Added a comment explaining apply_filter, added curly brackets to
disambiguate nesting in Wrapper_acquire, and re-indented to clarify.

      - Collector #928: DateIndex ignored timezones when indexing and
        querying

  - Indexes and Lexicon now much less likely to generate write conflicts.
    Previously *any* concurrent index/unindex operation would conflict

  - Performance and scalability fix for queries

being added to built-in types.

Jamie Heilman discovered it was possible for anonymous users to add
ZClass permission objects.  The newly created permission objects had
no real effect on security, but anonymous users should not be able to
do this anyway, so this patch fixes the bug.

The problem was that PermissionManager never got initiatized.  While I
was here, I took the opportunity to initialize other classes as well,
update the security declaration style, and apply the 'Define
permissions' permission.

Remove signals file, since the only signal you actually need to use is
for log-file rotation.

A few changes to the rST formatting.

  - Exterminate bare excepts
  - Port performance fixes from 2.6 branch
  - Add some comments to questionable areas
  - Simplify where possible
  - Add some spacing for readability (hahahahahah, sorry I crack myself up)
TODO: Fix inefficient __len__ and numObjects implementations

Remove dependancy on PlugInIndexes product by using randint directly to generate rids. randint now works properly with negative number in Python 2.2
Fix bare except. Simplify python implementation of safe_callable
