JOC: "Last Activities" tab is deprecated and only dispayed by a parameter if necessary

The development of the "Last Activities" tab in JOC has been stopped.

Please use JID (JobScheduler Information Dashboard) instead. JID provides an overview of the jobs planned and those that have successfully been completed. For more information about JID look at http://www.sos-berlin.com/doc/en/dashboard.pdf.

Reason:
This tab is very slow because it needs multiple commands to the JobScheduler and every command produced many database queries.

The JOC in JobScheduler release 1.5.3253 is the last release where this tab is shown. In later releases you can configure the ./config/operation_gui/custom.js to add this tab if necessary:

...
/*****************************************************************
*  flag wether the "Last Activities" tab is shown
*/
_display_last_activities_tab = true;
...
