Problem

Users want to be able to decide, if they want to search case-sensitive or insensitive in TM-Maintenance and same for mass deletion.

Solution

Support existing flag for case-sensitive search in TM-Maintenance.

If this is not possible to also be used for mass deletion, then disable mass deletion possibility in case a case-sensitive search is triggered.

By default search should stay case-insensitive, as it currently is the case.
