Create a link to today's notes folder in favorites

[pajoma]

Navigating to today's notes folder is to cumbersome. A folder in the user's default documents folder called Today's Notes always links to the current day. The link is updated (or checked) whenever vscode with active extension is started.

Open problem: When a file is moved into the Today's note which has not yet been updated, it will be saved in the old location (probably the notes folder of the previous day). We could circumvent this by checking the creation date of the previous notes folder, and move the files if of current day.
