Stylesheet link is media screen instead of all

[scottkellum]

via middleman/middleman#1240

When linking stylesheets like so:

<%= stylesheet_link_tag "main" %>

The resulting HTML is:

<link href="/stylesheets/main-e6a8fe78.css" media="screen" rel="stylesheet" type="text/css">

The resulting HTML should be:

<link href="/stylesheets/main-e6a8fe78.css" rel="stylesheet" type="text/css">

The result is that printed media does not pick up default styles. The screen media tag is dangerous because the spec indicates that TVs, handhelds, and projection won’t pick up these styles either. In practice only print styles fail because screen is so widely misused and TV/handhelds/projection are hard to test for.
