Make scrollbars and other controls tint/untint upon main window gaining

focus on Mac. This entails the following:
  - getting notifications that the main window has become or lost key
    window status (in BrowserWindowController) [new]
  - ... which tells the RenderWidgetHostView(Mac) to (de)activate [new]
  - ... which tells the RenderWidgetHost to (de)activate [new]
  - ... which sends a ViewMsg_SetActive message [new message] to the
    RenderView [new]
  - ... which tells the WebView(Impl) to (de)activate [new]
  - ... which tells its page()'s FocusController to (de)activate [new]
  - ... which is now in WebKit-land.

N.B.: "Activate" is the nomenclature used in WebKit; "focus"/"blur" can
sometimes (kind of) mean the same thing, but is ambiguous, since "focus"
has a more specific meaning.

Added a WebView unit test, which currently only tests to make sure that
SetActive() (and IsActive() [also new]) work correctly. The changes to
the other classes aren't very testable since they don't actually do
anything (other than pass things along).
