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.

Fixes #217
