Scheduled jobs list should be offered as a tab - just like individual jobs

In the most recent versions of TARGIT, jobs are edited in tabs, which is a great improvement, that allows users to jump easily from job to job, copy and paste settings etc.

Next step could be to offer the overview of scheduled jobs as a tab as well.

This could really improve the workflow, when going through the log of failed jobs - looking through each job and ad-hoc running them from the scheduled jobs list.
