Display "My Addresses"

This includes some demo code - ten seconds after the page is loaded, an address will be added to the wallet, then another ten seconds later.  This demonstrates how to request re-rendering of the page when we make a change to the wallet.  I'd like it to just update automatically whenever ANY change is made to the wallet, but I couldn't get the $watch to work for me.

Also, this has buttons for deleting and adding addresses - Ignore these for now, they're non-functional.
