Return the default client for use with a newly created browser window
(cef_browser_t object). If null is returned the cef_browser_t will be
unmanaged (no callbacks will be executed for that cef_browser_t) and
application shutdown will be blocked until the browser window is closed
manually. This function is currently only used with the Chrome runtime
when creating new browser windows via Chrome UI.
