The scaling factor can be given in the config file. When this changes,
images can be regenerated via POSTing to certain endpoints. It is
possible to regenerate just one attachment preview or all within a
collective.
This is the first available preview of an attachment wrt position. If
all attachments have a preview image, the preview of the first
attachment is returned.
Replaced semantic-ui with the drop-in replacement fomantic-ui [0]
which is a maintained fork. The fomantic-ui used here is a custom
build [1] of the less-version _without_ google-fonts (css-only). The
javascript part of fomantic-ui is not used, and also jquery could be
dropped now.

Issue: #349
Now, if the configured base-url is `localhost` (that is, it is left
unchanged), the request is insepected to retrieve the base-url value.
This is then used to set the `secure` cookie attribute. The `domain`
attribute has been removed from the cookie.
The notify-items task has been updated to use the same pattern for
creating absolute urls to items it its mail body.
The domain was incorrectly extracted from the request. It must be
using the `Host` header at last, trying now `X-Forwarded-For` and
`X-Forwarded-Host` first.
When `base-url` is the default (i.e. localhost), the cookie is now
configured with the domain doing the request and the webapp is
configured to run requests against the host in the address bar of the
browser.
