Change the spelling to "import random.seeded_random as random" and the
user fix is even shorter.

I do agree with the idea of continuing to provide a process global
instance of the current PRNG for ease of migration - changing a single
import is a good way to be able to address a deprecation, and looking
for the use of seeded_random in a security sensitive context would
still be fairly straightforward.

Cheers,
Nick.
