Feature Request: Jekyll kramdown images support

[andrzejQ]

Probably it is quite simple to add correction for Jekyll kramdown syntax, for example

kramdown in _posts folder:
![x.png]({{ site.baseurl }}/assets/img/x.png "x.png"){:width="20px"}
Markdown Panel:
![x.png](../assets/img/x.png "x.png"){width="20px"}

see: https://andrzejq.github.io/jekyll_1/jekyll/tests/2018/11/06/Test-MD.html and src

I've made some changes for test: https://github.com/andrzejQ/NppMarkdownPanel/tree/RegExp
