Added iPhone 6 and iPhone 6 Plus Scale Sizes

Using the iPhone 6 plugin will automatically scale the output image into the iPhone 6 resolutions without scaling the original ArtBoard. Useful for those designing in points (1x) rather than in pixels (Retina 2x / 3x) resolutions. (Plugin also detects Portrait and Landscape and scales accordingly).
