Add content item resolver

[bjarnef]

Currently we have a mediaItemResolver filter, which can be used in Block List and Block Grid custom views or label expression.

Umbraco-CMS/src/Umbraco.Web.UI.Client/src/common/filters/mediaItemResolver.filter.js

Line 4 in d34be8c

function mediaItemResolverFilterService(mediaResource, eventsService) {

But there is no contentItemResolver filter, which I think would be useful. We do however have the ncNodeName filter, but it only resolve the node name value - not any custom properties on the content node.
