Does not handle non-images

[esnalabu]

apod.nasa.gov sometimes post videos from youtube in the feed, this does not render well on screen. An url and an error message is show. I guess this can be cleaned in some way, like falling back to the last valid image or a default image.

This is now available with my new module: MMM-APOD !

MMM-APOD is an evolution of MMM-nasaastropic (thanks to NASA API):

• Supports image and video.
• Displays title, description and copyright.
