        Reviewed by Tim Hatcher.

        Test: manual-tests/inspector/highlight-source-line.html

        * manual-tests/inspector/highlight-source-line.html: Added.
        * page/inspector/ResourcesPanel.js:
        (WebInspector.ResourcesPanel.prototype.showResource): Call
        highlightLine on the view if that function exists.
        * page/inspector/SourceFrame.js:
        (WebInspector.SourceFrame.prototype.highlightLine): Added. Adds the
        webkit-highlighted-line class to the relevant line, then removes it
        after a short delay.
        (WebInspector.SourceFrame.prototype._loaded): Added styles for the
        highlighted line(s).
        * page/inspector/SourceView.js:
        (WebInspector.SourceView.prototype.highlightLine): Added. Calls
        through to the SourceFrame.
