CTRL+D, CTRL+X, and Alt+RightArrow -- Enables Auto "Due Date" Insertion/Quick Note Deletion/Indent Text (Simulated Tab) and the ability to visualize Overdue Notes.

[dustinsterk]

I wanted a way to quickly add the date to the front of a note and also indent the text since Tab is used to cycle notes. I have enabled auto due date insertion with ctrl+d and the ability to indent with Alt+ArrowRight. I also added a quick delete of a note with ctrl+x (as you do with the ability to quickly add a new note before or after current note).

In this PR I also added the Command+shift+* for the MacOS bullet bug but feel free to remove that.
