There was an issue introduced in commit 7b512a88 through the use of
the `slapos.cookbook:wrapper` recipe. This recipe cannot be used in
a component without causing a dependency problem; see 22124832 for
a more complete description of the issue.

I originally forgot to extend the monitoring stack, and the monitor
httpd port was previously not configurable.

Also, I refactored a few comments to have reasonable line-widths.

The font configuration is now the responsibility of
software/headless-chromium, and any other software releases that wish
to use component/headless-chromium.

This is necessary because Chromium needs to think that the Host header
is an IP address (for security reasons), but the browser needs to think
that the Host header is a domain name (for TLS purposes). The easiest
way to do this is to use the Nginx http_sub module, but this isn't
enabled in the default SlapOS Nginx build.

The nginx proxy configuration now works with websockets. It's now possible to use the remote debugging port from another machine! Note that you'll need to manually change the ws=[ip:port] parameter in the URL to wss=[server-cdn-url] still. I will see if I can patch the frontend page to not require this, but I wanted to commit a working version first.

Cloning the full source tree rather than just a snapshot at the desired
version does increase the size of the checkout, but not as much as
originally feared. It goes from 25 GB -> 31 GB, which is manageable.
On the other hand, this allows some automated tools to figure out the
commit hashes from the repository history, which prevents the frontend
from complaining.

I plan to clean up the buildout file in the future, but I just wanted
to commit a known-working version.

Also improve the recipe `switch-softwaretype' by catching the possible errors.

- directory html5as: final version 
- directory html5as-base: initial version
