            Bug ID: 177419
           Summary: Web Inspector: Create ResourceCollectionContentView
                    and make CollectionContentView easier to extend

          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector

Summary:
Create ResourceCollectionContentView and make CollectionContentView easier to extend.

CollectionContentView should be generic, work with any represented object Collection, and not perform any type checking. It should just map items to ContentViews using the provided ContentView constructor.

class CollectionContentView extends ContentView
{
    constructor(collection, contentViewConstructor, title)

    // Public

    addContentViewForItem(item)
    removeContentViewForItem(item)

    // Protected

    contentViewAdded(contentView)
    selectedItemChanged(previousSelection, selectedItem)
}

Subclasses can override `contentViewAdded` and `selectedItemChanged` to add behavior, such as toggling CSS classes or calling WI.showRepresentedObject.
