Applet example

[David Blevins]

The applet example should be able to setup the keystore and keys if  
they don't exist.  Seems we're also using the 3.1 version of the  
client which is going to break eventually when the protocol changes.   
We'll need to figure out a way to get that on whatever the current  
version is.

Not a super high priority but something we'll want to clear up before  
we release 3.1.1.
