Re-implement the screensaver to use WebView instead of ExtensionDialogHost.

Use WebView to render the screensaver extension instead of ExtensionDialogHost. Using the RenderViewGone override to detect termination of the renderer process to restart it.
Added browser tests.

R=ben@chromium.org,sky@chromium.org
BUG=chromium-os:28211
TEST=Tested that the screensaver comes up; tested the reload via crashing the extension renderer with SIG_ABRT; also ran browser tests.
