Improve font rendering by setting Electron background

[Lombra]

Electron has a bug (feature?) where if you don't set the window background to white, all text will use grayscale antialiasing. Set the background color to #fff in order to enable subpixel antialiasing, which makes text look much better.

For Bitwarden, you need to do it here:
