Provides the infrastructure for Browser unit tests that create a

BrowserWindow with only a TabStrip. I also converted two ui tests over
to unit tests to make sure it all worked. I had to add a bunch of null
checks to Browser and a couple of other places.

+// Base class for browser based unit tests. BrowserWithTestWindowTest creates a
+// Browser with a TestingProfile and TestBrowserWindow. To add a tab use
+// AddTestingTab. This adds a Tab whose TabContents is a TestTabContents.
+// Use the method test_url_with_path to obtain a URL that targets the
+// TestTabContents. For example, the following adds a tab and navigates to
+// two URLs that target the TestTabContents:
+//   AddTestingTab(browser());
+//   browser()->OpenURL(test_url_with_path("1"), GURL(), CURRENT_TAB,
+//                      PageTransition::TYPED);

+//                      PageTransition::TYPED);
+//
+// Subclasses must invoke BrowserWithTestWindowTest::SetUp as it is responsible
+// for creating the various objects of this class.
