Panic caused by empty args

Parsing an empty argument e.g. foo '' causes Command.Parse to crash here.

I've opened a PR request with a simple test and fix.

Panic when requesting non-existent argument

I mistyped one of the arguments in the command handler, which caused a panic.

My command was registered like this

add := clif.NewCommand("add", "Add a new package to the directory", addCommand)
add.NewArgument("packages", "The package(s) to install.", "", true, true)

And in my handler I had this:

func addCommand(cmd *clif.Command) {
    packages := cmd.Argument("package").Strings()
    fmt.Println("To install: ", strings.Join(packages, ", "))
}

If you run the code above you get something like this:

Numbered options sorting strangely with `Choose`

When providing Choose a list of keys incrementing from 1-10, 10 becomes the second option in the choice list (instead of two). I believe this is the sort order used by sort.Strings. It'd be great if Choose handled integer keys better, or maybe didn't sort the map at all. Further, perhaps there could be another function like Choose that takes an array of strings and automatically prints incrementing numbers as the choice.

Thanks
