v1.24.7
Viewer: add $$ syntax for inline formula

Since the version 1.19.8 Tp-Note can render mathematical formula. So far
inline formula had to be enclosed between `$ and $`. e.g. `$\alpha$`.
This former syntax, is still supported, is now deprecated.
The present release adds support for the standard syntax with simple $
enclosure, e.g. $\alpha$.

The former syntax for display formula:

```math
\alpha
```

can now be written as:

$$
\alpha
$$

v1.24.6
Revert migration to the `mdka` crate

The reverted change was introduced in v1.24.5. Unfortunately everyday usage
shows, that the `mdka` crate is not as mature as the former solution with
the `fast_html2md` crate.

Otherwise, no new features. The `extensions` table of the `zettel` scheme was
updated. This concerns only users of the `zettel` scheme _not_ using Markdown.

v1.24.5
Migrate to a different HTML to Markdown filter used in internal templates.

This release has no new features.
The `html_to_markup` template filter now resorts back to the `mdka` crate.
Unlike the previous dependency, this crate is published under the
Apache-2.0 license.

v1.24.4
Downgrade some dependencies to comply with rustc 1.77.2, no code changes

v1.24.3
Enhance the HTML clipboard configuration options

This release extends the `html_to_markup` filter by adding a `default=`
parameter in case the filter fails, its result is the empty string, or if
the filter is disabled for a certain markup language with the configuration
variable `extensions.1`.

The `clipboard` variable is replaced by the variables `txt_clipboard` and
`html_clipbaord`. They both represent the clipboard's text content. The
difference is, that the `html_clipboard` carries HTML formatting along the
text, while `txt_clipboard` holds the plain text only.
