Error pop-ups are impossible to read with a red screen filter

[Alistair M]

The error and warning popups at the bottom right, white text on a red background, are impossible to read when you have a red screen filter covering the display, like you do when you're outside and you want to keep your dark-adapted vision.

I suggest allowing the popup colours to be configurable from the settings screen.

Background for Warning and Error Messages can now be configured in the options.
