libcef:

- Add support for specifying the cache location (file path or in-memory) via a new 'cache_path' parameter to CefInitialize().
- Create popup windows with a NULL parent window handle so that they don't stay on top of the original application window.

cefclient:
- Properly handle address change and title change for popup windows.
- Add a test for creating a popup window.
- Define TEST_SINGLE_THREADED_MESSAGE_LOOP by default.
