Updated *.properties files to comment out the global.build.component in each *.properties file so modules are no longer built into a rollup build dir, they are expanded into a per module directory structure

Fixed widget extension/plugin meta-data to include host [Fixes #2529071] and sync'd couple of places where loader data was out-of-sync with YUI.add

Reducing widget dependencies, to just what the Widgetbase class actually uses + base-pluginhost. Dependency changes: requires base-base, base-pluginhost instead of base requires node-base, node-style, node-event-delegate instead of node Also, added base-build to the widget-* extensions, so that Base.build is present when you pull in any extensions; to minimize impact. Users who were implicitly relying on the complete node or base package which came with widget, will need to 'use' the missing modules. Fixes #2528653
