encoding/json: document unmarshalling of lowercase keys into exported struct fields

[cespare]

When unmarshalling a json object with a lowercase name into a struct with a field of the
same name capitalized, json.Unmarshal will match the object name to that struct field.
This behavior is the same in 1.0.3 and tip, and it is not documented on 1.0.3 or tip.

http://tip.golang.org/pkg/encoding/json/#Unmarshal

It would be good to point this out in the json.Unmarshal doc comment.
