Subject: [PATCH] Deal with ownCloud removal from Debian

It has been decided that FreedomBox will no longer support ownCloud due
it's removal from Debian.  To deal with this:

- Don't show ownCloud in Plinth any more for new users.

- For users who have already installed ownCloud, show a warning message
  that they need to migrate away from ownCloud or need to manage it
  manually.
