since clipcc is primarily aimed at Chinese users, and the official api is inaccessible in China, is using the official source by default a good idea?

same with #253, the editor itself shouldn't assume the running environment. for community's editor or a specific platform, it is ok to override the settings by default, through external json config or by other ways. however the editor itself should behave as scratch, we just provide a way to change api.
