Ability to add multiple files

We need the ability to add multiple files via a single zip.

A single zip could be uploaded, it would then be unpacked into single files and become searchable.

Please note that we still need the ability to upload a zip that is not unpacked so don't override that function (a checkbox or seperate section perhaps).

An optional extra to this feature would be to add multiple (of a definable number) upload dialogs with a filebrowse function

Stemming from my biggest pet hate to make lots of files searchable and accessable to other team members in a highly underresouced environment.
