[dev] [surf] patch for style toggling

[Nick]

Attached is a patch that enables toggling the user style on/off. It 
also adds an appropriate letter to the status thing in the title. It 
uses the key / letter 'm', only because 's' and 'c' (for style / 
css) are already taken. The patch is against tip.

I use this to switch between a dark style and whatever the website 
deems fashionable.

I think it should probably be applied to the main repo, as it's 
useful and small and good. If there's no interest in that I could 
add it to the website instead.
