Saved windows and internal settings share same namespace

[cspotcode]

If you save a window named "savedWindowNames" then all your saved windows disappear. I know this isn't exactly likely to happen, but it's still possible and straightforward to avoid.

A more likely example is naming a saved window "version" which would break the update messages.

I think the simplest fix is saving windows as localStorage['savedWindow-' + nameOfWindow];, essentially putting them in their own namespace.
