* conf/nginx-primaryonly.conf: Use tabs instead of spaces
* management/web_update.py: Includes the tabs so they display with the correct indentation when added to the local.conf

v0.50 (September 25, 2020)
--------------------------
Setup:
* When upgrading from versions before v0.40, setup will now warn that ownCloud/Nextcloud data cannot be migrated rather than failing the installation.
Mail:
* An MTA-STS policy for incoming mail is now published (in DNS and over HTTPS) when the primary hostname and email address domain both have a signed TLS certificate installed, allowing senders to know that an encrypted connection should be enforced.
* The per-IP connection limit to the IMAP server has been doubled to allow more devices to connect at once, especially with multiple users behind a NAT.
DNS:
* autoconfig and autodiscover subdomains and CalDAV/CardDAV SRV records are no longer generated for domains that don't have user accounts since they are unnecessary.
* IPv6 addresses can now be specified for secondary DNS nameservers in the control panel.
TLS:
* TLS certificates are now provisioned in groups by parent domain to limit easy domain enumeration and make provisioning more resilient to errors for particular domains.
Control Panel:
* The control panel API is now fully documented at https://mailinabox.email/api-docs.html.
* User passwords can now have spaces.
* Status checks for automatic subdomains have been moved into the section for the parent domain.
* Typo fixed.
Web:
* The default web page served on fresh installations now adds the `noindex` meta tag.
* The HSTS header is revised to also be sent on non-success responses.
* Only spawn a thread pool when strictly needed
For --check-primary-hostname, the pool is not used.
When exiting, the other processes are left alive and will hang.
* Acquire pools with the 'with' statement
This will make it so that the HSTS header is sent regardless of the request status code (until this point it would only be sent if "the response code equals 200, 201, 206, 301, 302, 303, 307, or 308." - according to thttp://nginx.org/en/docs/http/ngx_http_headers_module.html#add_header)
These subdomains/records are for automatic configuration of mail clients, but if there are no user accounts on a domain, there is no need to publish a DNS record, provision a TLS certificate, or create an nginx server config block.
When the management commands fail, they can print something to the standard error output.
The administrator would never notice, because it wouldn't be send to him with the usual emails.
Fixes#1763
* Create the mta_sts A/AAAA records even if there is no valid TLS certificate because we can't get a TLS certificate if we don't set up the domains.
* Make the policy id in the TXT record stable by using a hash of the policy file so that the DNS record doesn't change every day, which means no nightly notification and also it allows for longer caching by sending MTAs.
Folks didn't want certificates exposing all of the domains hosted by the server (although this can already be found on the internet).
Additionally, if one domain fails (usually because of a misconfiguration), it would be nice if not everything fails. So grouping them helps with that.
Fixes#690.
