Fix for bug 2252:
You can now choose to have the calendar "remember" your filter settings
between logins.
Some extra code in calendar/lib.php for DST. It doesn't currently affect
how Moodle works.
Includes preliminary support for DST!
Includes "admin sees all events or only own?" setting (bug 1972)
WARNING: Modified moodlelib.php to explicitly specify NOT-DST when
calling mktime() and gmmktime(). This is essential since we don't want
PHP to second-guess us for the DST matters, but... it may affect existing
code?
- simplified the screens some more (headers etc)
- preferences are all on one page, and the code was rewritten
for simplicity and consistency
Changes are not well tested yet but I'm off to bed :-)
Changed the handling of time display format; now it's read from the language
file by default, and a new preference has been added to allow each user to
manually specify his preferred time format.
