Allow anonymous non struct fields

[emilevauge]

Hi!
I'm facing an issue on traefik traefik/traefik#743 that prevents us from using an anonymous slice field in a struct:

type Users []string

type Basic struct {
    Users `mapstructure:","` // explicitly don't squash 
}

Calling Decode() on Basic will produce the error Users: unsupported type: slice.
This behavior is due to the test

mapstructure/mapstructure.go

Line 654 in a6ef2f0

if fieldType.Anonymous {

which I'm not sure is needed as few lines later you have

mapstructure/mapstructure.go

Line 673 in a6ef2f0

if fieldKind != reflect.Struct {

.

Commenting the first test fixes my issue.
What are your thoughts on this?
