Make input proceed and abort buttons work

[timja]

Added script and CSS from ConsoleNotes by outputting it from: h.generateConsoleAnnotationScriptAndStylesheet().

Re-registered JavaScript after adding to page with Behaviour.applySubtree

Note: There's a pre-existing issue in that if you click the proceed/ abort multiple times you'll get 404s then eventually a 500 in the server side logs, the issue is there in classic pipeline too

Fixes #568

Testing done

Used pipeline from #568 to approve and reject
