Herald - Kill Tabs

Summary: makes a nice side filter for most UI elements.  only place this getds a
little funky is on the test console; a second, inner filter list appears for the
"affected" filters.

Test Plan: viewed each side filter and verified ui.  for each filter, interacted
with the ui and made sure things looked right and there were no errors
