Implemented a "show paged list" link in Profile UI

As suggested in this PR https://github.com/NuGet/NuGetGallery/pull/2215 I implemented a link back to the paged package list, so that a user can navigate from the paged package list to the full package list and back again. This is only visible if paging is necessary.
