Closes #40 Notificaiton View Issue

Instead of making a new view to handle hiding the notification view, I
fixed the memory leak where each time a user created a new item, it
would create a new notification view and I set the notification's hidden
property to true to hide it until it is needed and then it unhides
itself, presents itself and then hides itself again.
Fix priceNotification memory leak

The price notification was being made everytime the user made a new
item. Now it gets setup once when the app is run and it doesn't already
exist.

#40 Notification View

Attach the notification view to the main controllers view instead
of the scroll view contained inside of the main view.
This prevents the notification from begin visible when the user scrolls
too high or invisible when the user scrolls too low.

#51 Share button

Had to do some moving around to fit the new share button.
The size of the navigation bar text "Delightful" had to be smaller.
Also, I added a space before and after delightful to center it better
and ensure it isn't cut off on the ends. Serialize data for sharing.
Quick fix Price Display

If the price was under $1 it wasn't being displayed.
Now the price displays for everything except $0.00
