Move bundled client-side resources (.js, .css) to META-INF/web-resources instead of META-INF

Placing resources in META-INF/web-resources is recommended by the new resource serving mechanism in Spring MVC 3.0.4. Moving bundled client-side resources (Spring.js, Spring-Dojo.js, Dojo Toolkit, etc) to the recommended location would allow applications to use this configuration:

<mvc:resources location="/, classpath:/META-INF/web-resources/" mapping="/resources/**"/>

Instead of this:

<mvc:resources location="classpath:/META-INF/dojo/" mapping="/resources/dojo/**"/>
<mvc:resources location="classpath:/META-INF/dijit/" mapping="/resources/dijit/**"/>
<mvc:resources location="classpath:/META-INF/spring/" mapping="/resources/spring/**"/>
<mvc:resources location="/" mapping="/resources/**"/>
