Taskwarrior uses "expire" to refer to deletion of tasks past their
"until" date, so let's use `purge` to link this semantically to the
`task purge` command.
This would be immediately useful to improve the rendering of the man
pages in third-party websites such as manned.org and the arch man pagesk
- https://mankier.com/1/task
- https://man.archlinux.org/man/task.1
The regular console output, or websites which render the manpage in
monospaced fonts, will not be affected by this change.
This change could also help with eventually rendering the manpages in
the documentation website, and having a mix of monospaced and variable
width fonts.
To test the HTML output:
```bash
git clone git@github.com:jacksonp/manner.git # used by ManKier
./manner/manner.php task.1.in >| task.1.html && $BROWSER task.1.html
```

This removes use of gnutls and the TLS implementation, which is no
longer needed (task synchronization is handled via Taskchampion, which
uses `reqwest`, which handles TLS via other Rust dependencies). This
incidentally removes the following config options:
* `debug.tls`
* `taskd.ca`
* `taskd.certificate`
* `taskd.ciphers`
* `taskd.credentials`
* `taskd.key`
* `taskd.server`
* `taskd.trust`
This also drops support for the transitional `json.depends.array`
configuration value, which has not been necessary since ~2016.
As with tags, dependencies are stored in both a "combined",
comma-separated format (for compatibility) and in an
attribute-per-dependency format (for the future).
Every configuration parameter can be overwritten for the
current context by setting the parameter:
context.<name>.rc.<parameter> = <value>
in the config file. This allows for example to set a custom
report for each context.
Per the beginning of the man page, the summary line should give the default value. This isn't the case in a few places, so I changed them. (No guarantees I found them all.)
