Build with a recent Closure Compiler is broken

When running the v86 built with the latest release of the compiler (v20141120), a Type Error (cannot read property of undefined) occurs.
This is because of mixing styles in using settings object, eg:
settings["load_devices"]
vs.
settings.load_devices
The former name is preseved, while the latter gets mangled, which causes vga not to be created.
I am proposing not to use associative arrays in settings.
