calendar 4.7.x-1.6

Version 1.6
===========

- 182998 Use Date API handling of timezones instead of Drupal default timezone offset when computing calendar values.
- Get rid of test for Date API since it's buggy and hopefully everyone already has done this.
- 157593 Make sure drupal_get_form gets a form array.
- 172073 Allow for non-calendar arguments before any calendar arguments to dynamically filter calendar.
- Remove date fields from default view to force user to add the right field. Tired of handling support questions about unexpected date fields.
- 171306 keep empty nodes out of ical feed.
- 166659 and 160378 clean up handling of header and footer on empty pages.
- 155701 and 167110 ical and setup tabs sometimes didn't show up. Needed to rework the logic of calendar_is_calendar() and calendar_views() to properly identify views that have calendar types or calendar args.
- 159326 slight correction to indicating 'selected' day in mini calendar.
- 134240 fourth ical argument is optional, add '=NULL' so it will always work.
- 115144 make sure multiple day nodes don't get title and teaser created more than one time.
- 165845 make sure empty days have empty days theme.
- 167141 change array union to array merge to keep from losing first ical item.
- 158910 make sure view tab has no access control.
- Stop adding label after node title in the default theme. Takes up too much space, and confuses people. Anyone that wants it there can do custom themeing.
- 171155 remove view-header from css, no longer being used.
- 176384 test for integer before checking calendar values.
- 175131 fix min height in IE6.
- 178839 get rid of use of 'Start' and 'End' in default themes. They sometimes show up when they shouldn't and take up too much room anyway. Anyone who wants them can add them back into a custom theme function.
- More cleanup of day and month themes.
- Check_markup was applied too many times to the day view, wiping out all html.
- Fixing the day view - view fields weren't getting added in correctly.
- 135296 Offset for date-specific timezone was using the offset field name instead of its value, so being ignored. This will fix problems where time was showing up in the calendar adjusted to GMT timezone.
- fix parse error when calling theme_nav_title.
