Add Electron options from the Window facade

[lightwalkernet]

On the window facade it would be helpful to have access to be able to add electron options such as webPreferences as in the example below. This is helpful with opening external websites inside of the app.

webPreferences: { nodeIntegration: false, contextIsolation: false, enableRemoteModule: true, }

Currently I don't see an endpoint in the WindowManger to allow for additional settings and options to be added to the Electron BrowserWindow

I would like to see this as well to be able to load local files directly in an img tag with file:///.

This isn't supported yet, but could be! webPreferences are just a JS object. Happy to review a PR that exposes this.

You can now pass webPreferences via the Window::webPreferences() method.
