Updated metadata for Widget extensions. Now each has a /meta/ dir.

Removed legecy 'path' property from all modules meta data files

widget-base is the skinnable:true module, not widget. Fixes use('widget') not pulling in widget css

Updated attribute, base, event-gestures, pluginhost, widget rollup meta-data to include use. Also removed unused widget/src/build.properties

Kweight refactor: Broke widget-base-ie out of the widget rollup, and added loader meta-data for conditionally loading it

Widget kweight optimization. UI_EVENTS and getSkinName functionality broken out of widget-base. No impact if you're using "widget". If you're using "widget-base" explicitly in your meta-data/use statement, you'll need to include "widget-uievents" or "widget-skin" if you need the broken out functionality. "widget-base-ie" has also been broken out. Still need to add conditional loading meta-data, but it's still included in "widget"

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

fixed redundant metadata. fixed submodule propagation of skin data.

Updated loader meta-data for widget-locale

Moved original widget strings impl to a seperate module - widget-locale. It is deprecated, in favor of the new Y.Intl external string package support

Added module-specific loader metadata json files and the script to put them together
