default timezone for collections

Is there a reason why you can't define a default timezone for newly created collections? 02-collection_default_timezone.patch The patch also includes a typo fix (bugging me for ages) and the removal of the use of CreateHomeCalendar.

With that patch it's possible to define i.e.

$c->default_timezone = 'Europe/Berlin';

as a default timezone, or

$c->default_collections = array( array( ... 'timezone'=>'Europe/Berlin', ... ), );

within the collections defaults.
