New Backup Command!

Easily backup your notes in git with the notepack backup command which does the following:

• Scans the Note base folders for any new and updated files (does not include files outside configuration specified base folders)
• Commits each new file individually with a commit message based on the first H1 found in the file's Markdown, or the name of the file (without any YYYY-MM-DD prefix)
• Commits all updated files with an "Update todos" message
