Allow to delete images

[Khoyo]

There is, AFAIK, no way to delete added Header/Logo/Footer images, since tapping them sends you to the image picker (where you have to select an image), and long pressing does nothing.

It is unfortunate when you import a .pkpass that use the barcode as the header, or when you add one by accident.

The same is true for barcodes. They are impossible to delete if you add one by accident (although that would not be often the case). More importantly though, if you set the barcode to empty it will not be deleted but instead only show the + and - icons, with no way to edit the barcode again.
