The unnecessary `random` package has been removed in favor of using the
`math/rand` package directly. Seeding of the random value from crypto
has been added to the `stringid` package to account for the change.
May need to add an equivalent seed to `namesgenerator`, but this is
often used with `stringid` and has collision protection.
