Feature/ngui bugfixes

Fixes for:

COOPR-457
ngui: cannot open cluster in new tab (unauthorized)

COOPR-64
Confirmations should mention item being acted upon

COOPR-512
Time remaining for each some steps defaults to 45 years
please comment these out, these tests don't server much of a purpose now without interacting with Coopr Server - we should get sauce/selenium working first.
