Previously, project_release had conditional code inside hook_view()
to embed the view of packaged local items if project_package was
installed. Now, project_package just embeds the view into the release
node via hook_nodeapi().

- project_package_release_nodeapi() is only invoked for nodes of type
  'project_release' so we don't need to check for that again.
- Instead of the more expensive COUNT(*) we can just select a single
  row from the respective tables to see if we need to embed the view.

This includes both a new view embedded on the package release node with
details about patches to local items, and a new magic 'patch count' views
field for the {project_package_local_release_item} table with a custom
handler that uses pre_render() to count all the patches from
{project_package_local_patches} for every package/item pair in the view.
Also renamed 'project_package_items' to 'project_package_local_items'
for consistency and to be more self-documenting about what it is.

Fix the remaining issue from [#1098536] -- fix another misuse of the taxonomy array that was preventing project_release_supported_versions from being updated sometimes.

Part of [#1098536]: Check values instead of keys on the taxonomy when checking whether or not this is a security release -- the array format is somewhat dependent on the permissions of the user :(

Minor issue related to #1098536: Fix exception that occurs when attempting to run some of the previously disabled simpletests.

Fix #1098406 reported by smartinm: Duplicate entry exceptions in project_maintainer_save() were breaking tests.

add 'non_metric' key to base class plugin for release metrics -- tells sampler the plugin is not a metric.

#889922 by dww, hunmonk, bdragon: Metric for counting the number of releases created in a given time period.

Cast the releases count to integer for mongo efficiency reasons because we can't trust the db driver to get the type of a COUNT right.

The filter on the block display only shows full projects, while the
filter is exposed on the page display (still defaults to full-only).

#1070008 by dww, webchick: Changed label on the project status selector to 'Full' instead of 'Official'.

Reverted "#1066522 by bdragon: Added a {project_release_file}.downloads column." for now, since I can't safely deploy this for real until after the Git migration.

#1059992 by danillonunes, dww: Fixed bug where project.js was not loaded when form validation fails.

#991466 by dww: Fixed the default filters on the project browsing pages to still exclude projects without releases (broken via revision 1.85).
