Allow defining sort order for `StatusIndicatorField` labels

[zackkatz]

It should be possible to define a custom sort order for the StatusIndicatorField. Currently, the sorting is alphabetical, which doesn't always align with the expected sorting.

The default statuses: 'Active', 'Inactive', 'Info', 'Warning', 'Error' should be in that order, but won't be when sorting.

The EnumField provides label and value; perhaps this should be applied to the StatusIndicatorField (and all fields?) so that sorting can be controlled.

@zackkatz I'm not sure we can enforce this. It is only a way the value is displayed through that field. The sorting is done in the Data Source, and the field has no influence there. Also, there are not other sorting options than asc and desc in DataViews.
