[FEATURE]: Crack statistics on pretask and supertasks

[rixvet]

Description

Feature Request
See how many cracks per preconfigured task (pretasks.php) and also supertasks (supertasks.php) are found.

Reason
Find out which preconfigured task and/or supertask are effectively and show them in a glance, without the need of manual statistics.

That could be a nice feature but if i'm not wrong, once a pretask/supertask are created to task, it is not a identifier. That would require some changes on the database, or even a new table for tracking.

or there could be additional logic to trigger calculations? but yeah that would not be as user friendly
