Systemwide config option

On system level it should be configurable, if it is obligated to set the segment-wide qm flag for a segment.

task-template config option

• In addition it should be configurable, if the qm-flag-checkboxes are shown or not
• On task-template level it should be configurable, if it is obligated to set the segment-wide qm flag for a segment. If the qm-flag-checkboxes are not shown (see previous option) but this option sets them to "obligated", this setting is ignored and a warn-message is written to the error-log.
• In addition it should be configurable, which qm-options are shown as checkboxes to the user

Final check, if a segment-wide qm flag is set for all segments

When the user finishes a task, it is checked, if the segment-wide qm flag is set for all segments. If not a message is shown, that the task can not be finished because of this. This message is shown independent if it is tried to finish the task from task overview or editor. This message shows a hint, how to filter all segments without segment-wide qm flag

Add status filter option "qm not set"

An option to filter all segments with "qm not set" is added to the filter of the qm column
