Another round of package updates. These are no direct Zope2 dependencies, but required to run all tests of all direct dependencies

Added an allpy interpreter that has the same egg set as the alltests script. Changed the checknew script to check all packages found on sys.path, instead of only direct dependencies of Zope2. Otherwise we'll miss out on new releases from the test-only dependencies

- added XXX comments to the regression tests (don't know how to run and fix them)

o Leave BBB imports behind in old locations.

Integrated zLOG package back into this package. There's really no reason why anyone should want to use that one stand-alone

release branch

o Added tests for previously-untested clients.

o Uupdate versions for new location:

  - zope.pagetemplate==3.5.0
  - zope.app.pagetemplate==3.7.0
  - zope.app.publisher==3.8.1

Catch up with the rest of the Zope Toolkit of the day and loose dependencies on zope.app.appsetup, zope.app.component and zope.app.container.

Updated packages: pytz 2009g, zope.browser 1.2, zope.container 3.8.2, zope.lifecycleevent 3.5.2, zope.location 3.5.4, zope.publisher 3.7.0, zope.testing 3.7.4.
