Significant API changes for issue #218:

- Replace CefHandler with a new CefClient interface and separate handler interfaces.
- Add support for virtual inheritance to allow multiple CefBase parented interfaces to be implemented in the same class.
- Replace CefThreadSafeBase with IMPLEMENT_* macros to support virtual inheritance and to only provide locking implementations when needed.
- Move the CefBrowserSettings parameter from CefInitialize to CreateBrowser.
- Add a new cef_build.h header that provides platform-specific and OS_* defines.
- Introduce the use of OVERRIDE to generate compiler errors on Windows if a child virtual method declaration doesn't match the parent declaration.
- Use NDEBUG instead of _DEBUG because _DEBUG is not defined on Mac. (issue #240).
