title: Rails 3.1.0 assets folder not rendering: Sprockets::Environment#static_root is deprecated
body: <p>When trying to update my rails 3.1.0.rc4 app to rc6, I must have messed something up because my assets (JS and CSS files) stopped rendering. I tried to revert to rc4, but was still having this problem. So I transferred all my files over to a new 3.1.0.rc6 app and everything appears to work fine, but I get the following messages:</p>
  <blockquote>
  <p>Sprockets::Environment#static_root is deprecated</p>
  <p>Sprockets::Environment#path is deprecated</p>
  </blockquote>
  <p>followed by a long list of files - I can attach the extended msg if needed. I'm guessing I inadvertently fooled around with the sprockets configuration and that's what's been messing up my app from the beginning. How do I de-deprecate/re-?configure sprockets I guess is my question?</p>
  <p>I've tried some different sprockets gem versions, but nothing has worked yet.</p>
  <p>Thanks.</p>
