Make the notes section more noticible

Currently the notes is not being used due to there being no indication as to if a product has notes or not. I suggest that next to the notes option in a product add '(#)' with the number of notes between the brackets. This way we actually know if there is any notes in the product or not. Or.. on the manage products page, add a column (similar to the archive column) for notes with yes or no answers (again, similar to the archive column) so we can actually tell if a product has notes or not. We need this so we can maker proper use of what could be a really helpful feature.
