v1.24.12

Maintenance release: replace HTML to Markdown library

This maintenance release migrates to the `htmd` library used by
Tp-Note's internal HTML to Markdown clipboard filter to improve stability.

v1.24.11

Breaking change: rename `.tpnote.toml` to `tpnote.toml`

The former marker filename was `.tpnote.toml`. As the marker file
and the configuration file `~/.config/tpnote/tpnote.toml` have the same
syntax and semantics, it is more consistent that they have the same filename.

If you have used marker files, please rename them from `.tpnote.toml` to
`tpnote.toml`.

v1.24.8

Group front-matter variables in templates

Breaking configuration change. If you use custom templates, please update them:

Front matter variables in templates must be preceeded with `fm.`, e.g.
`fm_author` becomes `fm.fm_author`, `fm_title` becomes `fm.fm_title`,
`fm_subtitle` becomes `fm.fm_subtitle` and so on.

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.

v1.24.4

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