[<pe...@us...>]

Update of /cvsroot/neuclear/neuclear-pay/src/java/org/neuclear/pay/receiver
In directory sc8-pr-cvs1:/tmp/cvs-serv29147/src/java/org/neuclear/pay/receiver

Modified Files:
	PaymentReceiver.java 
Log Message:
Refactored the whole signing process. Now we have an interface called Signer which is the old SignerStore.
To use it you pass a byte array and an alias. The sign method then returns the signature.
If a Signer needs a passphrase it uses a PassPhraseAgent to present a dialogue box, read it from a command line etc.
This new Signer pattern allows us to use secure signing hardware such as N-Cipher in the future for server applications as well
as SmartCards for end user applications.
