BUG: colour picker not working on safari

[Lottie16]

As reported during the presentation, the colour pickers for fold lines etc are not working on safari

eeeeh... just throwing it out there that I'm not likely to fix this as I only develop in Chrome.

Am using <input type="color" id="markup_fold_lines_color" value="#aaaaaa" /> to render the pickers -- if Safari can't fucking update their browser to support that, that's on them
