new LoggerConfigSaver( key )

Description

Automatically load/save Logger configs based on state changes.

This particular implementation is intended to be efficient but imperfect. Data, at least as far as high water marks, may be lost.

It monitors changes to Logger configs, and saves them to userscript storage as appropriate.

If the userscript enables the value change listener API (see below), that will be used to detect when values need to be reread. Otherwise, it will use the browser based visibilitychange event to reload.

// Enable in the ==UserScript== header with:
			// @grant GM.addValueChangeListener
			// @grant GM.removeValueChangeListener
