- Support runtime configuration of renderer-related preferences (issue #1501).

- Persist modified user preferences including per-host zoom settings when a cache_path value is specified and persist_user_preferences is set to true via CefSettings or CefRequestContextSettings. - Avoid the need to duplicate files from chrome/ by having CefBrowserContext extend Chrome's Profile class.
