The sort criteria for screen element "status of triggers" shall be optionally configurable in screen-edit to sort by date (desc), host (asc) or severity (higher severities first)

It shall also show the number of triggers active, as currently only the first (configured) are shown. Something like "10 of 947 problems".

If sorting is not set, it will be sorted as in 1.8.x. Otherwise it should be sorted by selected sorting criteria.

Sorting criteria should be displayed but cannot be changed by user, i.e. must be not clickable.
