use /dev/random per default

Why not using /dev/random per default?
Isn't it anyway only used in luksFormat or when adding new keys (which happens only rarely)?
Sure it could block in batch applications, but it's generally questionable whether encryption makes that much sense there... and if they need it, they still could use the command line option for urandom.
And we should always default to the most secure settings.
