Updated Scrapbook Pages and Trash Can Functionality

Hey!

Quick update on Picture This!

I edited the scrapbook page for both sides to update with the page selection and share the image. 

I also edited the trash can asset and refined the deletion of the sticker functionality slightly. I added a transparent image where the trash Icon is, which deletes the image when hovered over. This creates a larger area for the sticker to be deleted in and reduces the need for moving around to find the right spot. 

Unfortunately, if the sticker is scaled past a certain size, it still won't let you delete it until it is scaled down. I've noted that down as an issue and plan to address it at a later time.
