We now just use JSON.parse and JSON.stringify - it's supported by all
browsers supported by the client.
Tools.safeJSON has also been moved to Storage.safeJSON, since it's not
used in replays at all.
jslider was incredibly buggy, and most likely the cause of the problems
with the teambuilder on mobile, and required some pretty ridiculous
hacks, and leaked memory.
We're now using HTML5 sliders, like we are with the volume controls.
HTML5 sliders aren't supported by IE9, but they're supported by most
other browsers PS cares about. If not, well, they won't look too ugly
probably...
When loading a background, we use Color Thief to get a six-color
palette from the image, for use on the main menu buttons.
Only hue and lightness are extracted.

Backgrounds are now stored in localStorage in the current origin,
rather than the prefs origin. This allows faster loading, as well
as different backgrounds for different origins, which other
servers should like since it means their backgrounds get seen
at least once before possibly being replaced.
Special thanks to Joim for the base code.
