The changes are:
 * `*Runnable` -> `*Task`;
 * `RunnableMsg` -> `Task`;
 * `RunnableWrapper` -> `TaskCanceller`;
 * `MainThreadRunnable` -> `MainThreadTask`;
 * `wrap_runnable` -> `wrap_task`;
 * `get_runnable_wrapper` -> `task_canceller`;
 * `handler` -> `run`;
 * `main_thread_handler` -> `run_with_script_thread`.
