v0.2.13

Hotfix for v0.2.12. / v0.2.12 的热修复版本。

• Closing any window on Windows no longer pops "A JavaScript error occurred in the main process — Object has been destroyed": the renderer-recovery cleanup ran inside the window's own closed handler and touched the already-destroyed webContents. All v0.2.12 improvements are included.
  Windows 关闭任意窗口不再弹出 「A JavaScript error occurred in the main process — Object has been destroyed」：渲染器恢复的清理逻辑在窗口自身的 closed 事件里访问了已销毁的 webContents。包含 v0.2.12 的全部改进。

Windows users: install this instead of v0.2.12. / Windows 用户请直接安装本版本，跳过 v0.2.12。
