Remember the state of angular components when navigating back to the previous page

[tschaffter]

Issue: The user is looking for a resource on the Resources page. First he selects the Report radio button, set the search order to chronological, type 'Methionylthreonylthreonylglutaminylalanyl...isoleucine' in the search field and click three times on the button More Results. He then clicks on the resource, navigate to the page of the resource before figuring out that it's not what he is looking for and needs to go back to his search. Upon using the browser Back button, he find himself back to the search page but all the filters have been reset.

Suggested solution: find a way to remember the state of a page (including vertical scroll bar position) and restore it upon returning to it using Go Back.
