Seeds the Math::Random::MT::Auto generator automatically when present
in MCE::Hobo, similarly to Math::Random and Math::Prime::Util, to avoid
child processes sharing the same seed value as the parent and each other.
The new seed is computed using the current seed.Updated MCE::Shared::Cache to support optional argument "expires_in" for
set and sugar methods.Updated MCE::Shared documentation.
Bumped MCE dependency to 1.837.
