More external links
Add custom redirector to clear referers

We removed external links in #206 because Tor Hidden Services leak
referers (https://trac.torproject.org/projects/tor/ticket/9623).
Obviously this isn't ideal because of the usability tradeoff.

One way to get around this without using Javascript is to replace all
external links with a link to a blank SecureDrop page that does a meta
refresh to the external link, since meta refreshes always clear referer.
Use custom redirector for external links
Avoid namespace pollution, add comments
Confirm before deleting collection
Confirm before bulk deletes too
updated install script for scrypt
apparmor update for scrypt

Merge branch 'feature/confirm-delete' of https://github.com/diracdeltas/securedrop into diracdeltas-feature/confirm-delete

they won't work with the CSP that we set by default in production (and are not
best practice)

more informative confirmation messages

ignores nonsensical request to delete multiple collections if no collections
are selected
