Widget Settings build process

Build process:
- Concat and minify css
- Concat and minify js
- Moves locales and html files

Updated folder structure

Updated jquery to 1.11.0
Good question. Currently I'm keeping the folder structure intact when moving these components to dist. settings.html which references this html file is in the dist folder directly, so the folder reference is needed. However, this component is removed in the next PR and moved to the widget-common-ui-components repo. Thanks.
