stylesheet_link_tag should overwrite 'media', not :media

[MartinKoerner]

options = sources.extract_options!.stringify_keys
options[:media] = 'print' if options[:media].blank?

In the first line, every key is converted to a string, in the second line you look for the :media key
Maybe

options["media"] ||= 'print'

is better?

Can options[:media] be a empty string? The actually code cover this, your example not.
