1.4.0

What's new

Apple pass builders can now set a background image, matching what the docs and Apple's pass spec describe for event tickets. Previously only setStripImage and setThumbnailImage were available.

EventTicketPassBuilder::make()
    // ...
    ->setBackgroundImage(public_path('images/background.png'))
    ->save();

A remote variant, setRemoteBackgroundImage(), is available as well. The image (along with its @2x and @3x densities) is bundled into the generated .pkpass.

Implemented in #50, closes #49.
