Pack the RenderResults and Renderlayers to the blend file

Hello

its quite frustrating that after you did a 4 hour long render + 2 hour on the compositor, the render that you work on disapear if you forgot to export the image.

saving the image or not, after closing blender and re-opening it your precious render should stay in the .blend

it should be like opening photoshop, your hard work should stay there and not being deleted.

(yes of course you can do an output node set up but its quite hidden, the precious render being save in the .blend should be an evidence)
