Redux-devtools: [redux-devtools-inspector][redux-devtools-log-monitor] Sort JSON tree keys alphabetically

[zalmoxisus]

As started in https://github.com/alexkuz/redux-devtools-inspector/pull/80, we need an option to sort keys, which was just merged (without using a function) in alexkuz/react-json-tree#108.
The suggestion is to add it to the props of the monitor, then adding the ability for changing this prop from the extension's settings page (another PR later). For the second part better to wait for the new UI, where settings will be a tab in the app, instead of using browser option page and syncing from there (that would imply rendering the monitors asynchronously when we get the options, so better to wait till we have the options right in redux store).

This would be a great feature! It has been indicated that this will be included in the 3.0 release. Is there a timeline for that?
