Deployment of Category Jail for Trackers

What has to be done

tiki-list_trackers.php categories support (currently missing so cannot filter by Perspectives)
tiki-admin_trackers.php: the same applies for listing
(the Create/Edit Tracker "Categorize" seems to be already filtered properly)
make sure it works with tracker wiki plugins
make sure search tracker items displays only results respecting the perspective view
since last visit module displaying new tracker items by category jail

the Create/Edit Tracker "Categorize" seems to be already filtered properly by Perspective view (Category Jail)
