Update 'kitchensink-angularjs' quickstart to demonstrate PUT & DELETE functionality

As it stands the kitchensink-angularjs quickstart only provides examples of those simple HTTP methods supported by html forms (GET & POST). When using a framework like Angular.js this is unnecessary and could be misleading for people new to client centric web development.

I would like to update the quickstart in the following ways to address this:

• Add an updateMember(Member member) method to MemberResourceRESTService.java (http://git.io/1CyYUA), annotated as a PUT route.
• Add a removeMember(Member member) method to MemberResourceRESTService.java annotated as a DELETE route.
• Modify/Add to the appropriate Angular partials and controllers to expose this new functionality to users.
• Update RESTTest.java (http://git.io/zIFs4g) & KitchenSinkAngularjsTest.java (http://git.io/Kk_shw) to account for the new routes.

If these changes seem useful to you and you would appreciate a pull request, let me know.
