Smooth scrolling toggling is currently wonky on runtime, since,
most of the time, it doesn't toggle on and off properly.
In addition, now that we have multi-window support,
the current implementation was somewhat lacking.
This commit solves those issues by replacing
the existing smooth scrolling related channels with a
new generic `relaunchRequest` channel.
The `remote` module is deprecated and `@electron/remote` is unnecessary,
since the `ipcMain` and `ipcRenderer` can replace their functionality,
providing better performance and better security.
All other dangerous calls (mainly pulling main process constructs into
the renderer process) have also been removed.
