4c0bc1fd88 Add program_ids() methods 
Added CompiledInstruction::program_id() so that we don't need to pass
around instruction indexes just for Message::program_id().

Also added Message.program_ids() that returns a slice so that we
can move those pubkeys into Message::account_keys.

2ab50cbae8 Move untested code out of SDK 
verify_signature() was only used in a test that was testing
binary layout. It only worked because the test transaction only
had one signature.

from() was only used by verify_signature() and that's something
we'd typically called `pubkey()`.

hash() didn't return the hash of the Transaction, as you might
guess. It's only used for PoH, so move it into Entry.

ae4d14a2ad Introducing Scripts 
A sequence of instructions. A client compiles the script and then uses
the compiled script to construction a transaction. Then it adds a

processing.
