Change table sorting behavior default

[billingb]

Introduce new sorting for tables that is:
1st column click -> assign primary sort
1st column clicks on columns not yet clicked -> assign secondary, tertiary, etc

2nd column click on already sorted column -> reverse sorting from ascending to descending on that column
3rd column click on already sorted column -> remove the sorting on that column

This new behavior should be added as the default behavior with a configuration option for the current sorting behavior.

Vuetify example that shows this behavior: https://vuetifyjs.com/en/components/data-tables/data-and-display/#multi-sort

Interesting. I find that vuetifyjs example to be more complicated than I have seen anywhere else, and because it isn't familiar it took some time to play and figure out how it worked. But because it is self-consistent and has sufficient visual cues to help figure it out, I think it could be OK as our default for tables. Normally I'd expect an opt-in for changes to existing behaviour but in this case, because it isn't breaking and includes the UI and style changes to help immediately see and work with the change in behaviour, I'm OK with changing the default and providing an option to revert behaviour.
