Missing bootstrap input states

[devsergiy]

There is missing styles for such states

• .has-warning
• .has-error
• .has-success

[devsergiy]

Could be implemented in such way

.has-error {
  $border-color: $state-danger-text;

  .chosen-container .chosen-single {
    border-color: $border-color;
    @include box-shadow(inset 0 1px 1px rgba(0,0,0,.075));
  }

  .chosen-container-active.chosen-with-drop .chosen-single {
    border-color: darken($border-color, 10%);
    $shadow: inset 0 1px 1px rgba(0,0,0,.075), 0 0 6px lighten($border-color, 20%);
    @include box-shadow($shadow);
  }
}
