* simplify it. Go from six checked-in config files + one local one to
three checked-in configs + commandline options. I find it less
confusing to have the options plumbed through fewer layers.
* support developing against a https production server, as described in
guide/developing-ui.md.
* fix the source map. The sourceMap parameter in prod.config.js as far
as I can tell evaluated to false when run with production config, and
anyway UglifyJS seems to be incompatible with the specified
cheap-module-source-map. Use source-map instead.
* Various settings in settings-nvr.js module
* settings-nvr-local.js can override settings-nvr.js
* settings-nvr-local is unchecked file
* Both files can be straight maps, or functions returning maps
* webpack env and args available to those functions
