Live REST API & Dso list component

fixed an issue where the pagination would always open on the first page if you went to the URL of a different page

replace ng2-truncate with a naive own implementation, because ng2-truncate isnt compatible with the AoT build

made use of embedded resources for relationships in the response that contain a single link for a set of resources rather than enumerate the self link of each resource

fixed an issue where sometimes the wrong resource would be returned if it was fetched as part of a list, and later queried as a single resource
