subscriptions 6.x-1.1

This is version 1.1 of Subscriptions for Drupal 6.

There are two major changes since 1.0:

• Fixed processing of digest mails, especially for sites that exceed the number of notifications that can be sent in one cron run (#350077: Maximum number of notification to send per cron job breaks Digest mode).
• Implemented a work-around for a core bug that was introduced in Drupal 6.14 (#193383-106: set_time_limit: Centralize calls and prevent warnings and errors).

The changes in detail:
Enhancements:
- Update .pot file and German translation, tune some strings.
- #581644: Provide a (temporary) work-around for bug in D6.14, which disables the cron job, and improve warning messages.
- #505480: Display number of entries in the queue and provide a button to clear the queue.
- #560146: Allow specifying a cron job time percentage (including 0 to temporarily disable notifications).

- #560146: Fix digest Subscriptions don't send if not set to "published" before cron runs.
