- Removal of Services. You can now access the adapter and utiliy

  registry directly via the site manager's `adapters` and `utilities`
  attribute, respecitvely.

  + Converted Principal Annotation Service to be a utility. Added
    database evolution code to convert all service instances to
    utilities.
  
  + Converted FSSync Service to be a utility.

  + Created the concept of a global site manager. The adapter and
    utility registry, formerly the adapter and utility service, are now
    managed by the site manager.

  + The `zope.app.utility` package has been merged into
    `zope.app.component`. The utility registration class is in
    `site.py`. The utility vocabulary is in `vocabulary.py`.

  + The `zope.app.site` package has been merged into
    `zope.app.component`. The site code can be found in `site.py`.

  + Fixed persistent modules code. Persistent modules are now simply
    utilities providing `IModuleManager`. The local site manager also
    does not know any thing about persistent modules anymore.

  + Updated `zope.app.pluggableauth`, so that it will work as an
    authentication utility.

  + Restructured `zope.app.persentation` (a.k.a page folders) to the new
    component API.

- Simplified the registration framework by only supporting two states:
  active and inactive. This allowed us to get rid of the registration
  stack and the complexity it introduced to the site management.

- Removed all presentation-related APIs from `zope.component`. This
  included the removal of presentation-related interfaces and the
  deprecation of all view-related API functions. One should use the
  adapter API functions instead.

- Implemented some initial deprecation framework, see
  `zope.deprecation`. It allows one to deprecate methods and properties
  in classes as well as any name in a module.

- Moved reusable test setups/APIs from `zope.app.tests` to
  `zope.app.testing`. No reusable testing code should be in a `tests`
  package or module.
