- Added new `renderer::Windowed` trait. This shoud allow users to easily try different renderers by simply changing one line. - Renamed `UserInterface` traits to `Application`, as the `run` method takes total control of the current thread. - Moved `MouseCursor` back to `iced_native`. The new `renderer::Windowed` trait returns one on `draw`. - Split `iced_native` renderer in multiple modules, for consistency.
