ikiwiki/ news/ version 3.20180105

ikiwiki 3.20180105 released with these changes

- emailauth: Fix cookie problem when user is on https and the cgiurl uses http, by making the emailed login link use https.
- passwordauth: Use https for emailed password reset link when user is on https.
- Remove openid provider icons from login selector, since openid providers are increasingly not working. Verisign retired theirs, and aol and yahoo/flickr are not commonly used for openid. Any users who still clicked those icons to login will need to instead enter their openid url.
- Updated German basewiki and directives translation from Sebastian Kuhnert.
