Title: Quality warning+workaround for Heroku+ImageMagick

Heroku has a known issue with its old version of ImageMagick providing inferior product images. There's an easy workaround floating around a few Spree issue threads. Since this isn't actually a problem that the Spree codebase can fix it seems appropriate to add the workaround to the docs instead.
