[Console] Sort autocomplete values alphabetically

I'm not sure if autocomplete matches should be sorted or not, so I've created a Pull Request to discuss. Either:

a) Matches can be scrolled through (with arrow keys) in the order they are originally supplied in the `$autocomplete` argument. This way the developer can prioritise certain matches over others.
b) Matches are sorted alphabetically. This makes the experience a little bit better for the user as they can anticipate when an item is coming up instead of browsing a seemingly random list.
