Update to bootstrap 0.12.0 to fix tooltips

See: https://github.com/angular-ui/bootstrap/issues/2828
Alternatives to upgrading were:
  - Add hack tooltip directive that adds the trigger/placement attrs
    to each tooltip
  - Manually add trigger/placement attrs to each tooltip in the src

Update had breaking change where dropdowns require the
dropdown and dropdown-toggle attributes, not just the classes.
Should have been this way anyway, so the attributes were added to each
dropdown.
These were removed because the angular ui bootstrap directives replace, rather than augment, the original js.
