FileTea

Created by: JosephKiranBabu

Integration of FileTea service (#839 (closed)) into FreedomBox.

Sharing files is still difficult though we have integrated Syncthing (which is folder-sharing). A volatile file sharing service can make sharing files painless for FreedomBox users.

Authentication

I have added Apache Basic Auth for the files shared via FileTea, which means that the receiver of the file should also be a Plinth user on the same FreedomBox. I am not sure of this decision. Can be convinced otherwise. The default permissions for FileTea is "anyone with the link can access". I turned it into "only logged in users of Plinth can access".
