Links to other notes or files are now possible in QOwnNotes

Build 25 of QOwnNotes brings better url handling in the markdown preview mode. Links to other notes or files are now possible!

Examples:
- <note://MyNote> opens the note "MyNote"
- <note://my-note-with-spaces-in-the-name> opens the note "My Note with spaces in the name"
- <http://www.bekerle.com/QOwnNotes> opens the webpage
- <file:///path/to/my/file/QOwnNotes.pdf> opens the file "/path/to/my/file/QOwnNotes.pdf" if the operating system supports that handler

You will find the new binaries in the download area of the project page.
