KMarkdownWebView (kpart) in KDE Review

[Friedrich W. H. Kossebau]

Hi,

KMarkdownWebView today entered KDE Review. This repo contains a kpart for 
rendered display of Markdown files, using web technologies (webpage with 
JavaScript library which creates HTML from the plaintext handed in).

I consider it rather a hack and would favour something done natively in Qt 
(e.g. like the Markdown Okular generator in https://phabricator.kde.org/
D7382). But for now it serves the use-case of providing a webpage-like 
rendered display of markdown documents. Especially for the live preview 
plugin for Kate & KDevelop currently worked on*.

See also https://cgit.kde.org/kmarkdownwebview.git/about/

The separate library libKMarkdownWebView is done for sharing code with a 
thumbnailer plugin, whose code yet is to be committed to this repo, as it 
resists to work right now.

Initial build on CI looks good:
https://build.kde.org/job/Extragear%20kmarkdownwebview%20kf5-qt5%20SUSEQt5.9/
https://build.kde.org/job/Extragear%20kmarkdownwebview%20kf5-qt5%20FreeBSDQt5.7/

And people on #kde-devel & #kdevelop also reported successful builds and 
usage.


Target would be extragear/$SOMETHING, with $SOMETHING possibly "utils".

Initial release planned right after leaving kdereview.

Question: is there any appstream metadata possible for plugins?

Cheers
Friedrich
