	Add order notes to the orders CSV export in Paid Memberships Pro

	Add this code your active theme's functions.php or a custom plugin.

	This may get moved into core at some point. We were worried about exporting the notes into the CSV
	because it can contain arbitrary text that could break the formatting of the CSV. With this code
	the export seems to handle quotes and commas fine when loading the CSV in Excel.
