subscriptions 6.x-1.0-beta5

This is the fifth BETA version of the Drupal 6 port of Subscriptions 5.x-2.x.

We do not recommend installing it on a production site, but we encourage you to test it and provide feedback (both good and bad!) in the issues queue. See #273505: Subscriptions for D6 is released! for details.

Changes since BETA3:

- #339076: Decode entities in CCK field values.
- #305235: Make 'Subscribe' links compatible with Pathauto.
- Provide an upgrade path for the D5 mail templates (requires latest mail_edit, see #318324).
- #336952: Warn about IP as site address.
- #333818: Fix E_NOTICE.
- #328341: Make pgsql CAST()s conditional on the database engine.
- #322131: Really fix user default subscriptions forms.
- #322131: Fix user default subscriptions forms.
- #318150: Get by without hook_nodeapi('prepare') for inserting nodes programmatically.

Changes since BETA4:

- #351606: Fix deprecated call-time pass-by-reference.

(This quickly supersedes BETA4, so I'm marking it with "New features" again.)
