encoding/gob: package documentation doesn't tell that only exported fields of a struct are encoded

[gopherbot]

by jbvanpuyvelde:

It's not written on the page http://golang.org/pkg/encoding/gob/ that the unexported
fields of a structure will not be serialized.

I took me some time to find the thread [1] where it is explained (it is also very
quickly said in the json package doc).
