Feature Split Wallet: Shares distribution

[CodersBrothers]

When you want create a split wallet now bitaddress generate plain shares. This is a big problem, you need trust in the manager or the distributor.

I'm thinking in this: The possibility for add a public key for each share before press generate shares. Then the shares are encrypted with the combination of public keys. The result will be shares encrypted, that each person can decrypt with their private keys, without other people in front.
