proper handling of coin with age restriction

Browse Source 
When a coin with age restriction is used for payment, the contract might
or might not require an attestation of minimum age.

When it does, we sent the signed minimum age along with the whole age
commitment (array of pubkeys).

Added:  When the contract doesn't require a minimum age, we still sent
the hash of the age commitment, as this is needed for the deposit of the
coin.
