Shader Nodes: added alpha mode selector to Image Texture node
Enables image user nodes to display the file alpha mode, similar to the
colorspace setting.
Also removes image_has_alpha in favor of using BKE_image_has_alpha, because it
did not check if the image actually had an alpha channel, just if the file format
was capable of supporting an alpha channel.
