Draft: README.md Preview Panel
Disclaimer: This is very WIP, and buggy. Also, I don't have much experience with developing for KDE so feel free to comment.
This is a panel that, when enabled, shows up whenever a README.md is detected in the current folder, and is hidden otherwise. It currently uses MarkdownPart, though I am pondering on whether to use QTextBrowser directly.
Let me know what you think!
