Create FreedomBox apps for existing Debian packages/services

As mentioned in our monthly progress calls, there are a number of services already available in Debian, that may be appropriate & ready for use in FreedomBox. I think it would be good to list them here:

Completed:

• radicale
• tahoe-lafs (removed from unstable/testing)
• tt-rss
• quassel
• samba
• mediawiki
• tt-rss (in progress)
• minetest-server
• infinoted (gobby server)
• searx
• gitweb

Consider adding:

• bepasty
• movim
• zoph
• git-annex
• wordpress
• rygel
• nfs
• ciderwebmail
• print server (cups)
• asterisk
• yate (SIP)
• drupal
• sogo
• janus
• dovecot + exim + spamassasin + clamav
• citadel
• ajaxterm
• mpd
• gnunet
• bitlbee
• jupyter-notebook
• diaspora (available in unstable only)
• squid (caching web proxy)

Please edit or comment if you know any others to add, or if there's any issue with adding a particular service.
