Remove old Tor versions from recommended server versions

Important updates got released lately, recommended versions should be updated accordingly.

only the following tor versions should be recommended: 0.2.5.16, 0.2.8.17, 0.2.9.14, 0.3.0.13, 0.3.1.9 and 0.3.2.6-alpha

motivation:

• legacy/trac#21394 (moved) DNS issue for exits http://arthuredelstein.net/exits Arthur and I are trying to reach out to affected operators but some have no contactInfo, increasing the recommended versions would at least show them some information in their log entries.

• legacy/trac#24244 (moved)
• legacy/trac#24245 (moved)
• legacy/trac#24246 (moved)
• legacy/trac#24333 (moved)
• legacy/trac#24430 (moved)

debian packages via deb.tpo are available, lets make this change once 0.3.1.9 is available on FreeBSD repos (I'll post to this ticket when that happens).
