This commit adds the new devices supported since v2015.1.2, a brief summary of new features and bugfixes to the release notes.
As the deactivation of the HT-mode setting in site.conf might be non-permanent and still setting it doesn't cause any problems, it is not needed to be mentioned in the "Site changes" section, I think.
When rebooting the node in config mode, currently the fastd key is
forcefully displayed in a fixed format. This is confusing in communities
where fastd accepts all keys and no key submission is needed.
Furthermore, some communities might want to personalize the display of
the key (see #387).
This patch moves the displaying <div> from the package's lua file to the
translation files of the sample site configuration and mentiones the
change in the release notes.
