Add a auto-generated text picture to games with no picture#151

Add a auto-generated text picture to games with no picture.
Many not popular games doesn’t have a picture, and that’s could be ok considering how huge a database like that is but at least it will be good having a text with the title of the game as a substitute picture because in things like the collection there is no way you can see what that games are if not clicking on them and seeing their pages.

@Exiled Eye This does actually already exist on the mobile app but I need to update the website to match :)
