scheduler 5.x-1.13-rc1

This is mostly a bugfix release, addressing the following issues:

• #230836: CCK date field shows blank after the node is published.
• #236841: Publish dates no longer work if time part omitted
• #190860: Scheduler unpublishes nodes when "Publish on:" date is set to the past.
• #245967: Add sort information for views
• #249299: Create new German locale file for version 5.x

There's some changes which probably need a little more testing, so here's the release candidate. If no blockers show up in a week or so, I'm going to make the official 5.x-1.13.

Enjoy!
