Improvement of Duration Fields in Conditional Formatting

The conditional formatting in lists did not work correctly when comparing two duration fields. The duration was previously interpreted as text, so for example 2:00:00 was seen as larger than 12:00:00. We have resolved this. In addition, the operation of the filter button on the column header of duration fields has been adjusted. Previously a list was shown with all values present in the list, now a 'number' filter is shown, where a from/to can be specified.
