Use md4qt to parse and render notes
While the current implementation of the parser does the job, it still has some issues:
- Wrong rendering in some corner case
- Hard to extend without touching the core of the parser directly
- Not up to date with the latest spec
- Lot of code to maintain while the focus of the app should not really be on this part
For those reasons, KleverNotes will now parse and render its notes using the md4qt parser. It is up to date, easily extendable and well maintained.
And thanks to a close collaboration with the author, new ideas can be brought to life easily.
Note: This merge request disable the link to a header in the note linking plugin (see issue 17). Clicking on one of those link will simply land the user in the corresponding note.
