Merge to a note via rules

- IF note contains/starts with / etc. AOEUAOEU then MERGE that note to a particular existing NOTE (instead of just the section), and have the option to include the DATE.

- So that anytime I make a note about my brother (Ron) I end up with a running account of all his notes. This just simplifies selecting and merging the notes, and when they merge now I lose the DATE if it's just a Titled note.
