Better defaults for config paths
Fix calendar tooltip ids overlapping, causing the wrong tooltip to display

Some days on each calendar are "gray" dates, that are of another month
than the month the calendar is about. Those should not get a tooltip id,
as that will cause problems when another calendar is displayed on the
same pages, where those dates aren't actually gray.

Always use 6 rows on a calendar for consistency
