Random#srand
Random#srand reuses old RNG for the return value

This should fix one of the failing specs.
Merge branch master into random-srand
Take 4B of /dev/urandom and time.time to make seed
Seed with time only if /dev/urandom is absent
# remove array copied methods
Merge branch 'master' into random-srand
Random.srand passes the last spec
moving method to objspace
# not need to check block
fix
array#comparison
# fixing flatten
