Sort available groups alphabetically in UI

[ghiculescu]

A minor nuisance when enabling a feature for a group is that once you have quite a few groups, they show up in a random* order. IMO the UI would be easier to use if they showed alphabetically.

• technically they show in the order they are defined in your code.

I only changed this at the view layer, I wasn't sure if you want to sort groups alphabetically everywhere they're interacted with.

Seems like a great idea.
