beter attachments shortcuts management: delete multiple links, see original task id and attachment name, mass edit expiry date

There is possibility to create shortcuts , esspecially public, to attachments in tasks.

But management of those link is very cumbersome eg. deleting is requied one by one, from the list of links it is impossible to see to which attachment and in which task, the link is created.

So I vote for features on shortcut list page:

- adding column for displaying original task number, as well as attachment name

- checkbox for mass actions:

-- deleting shortcuts

-- changing expiry date on shortcuts
