Addressbook feature

[kastolars]

Suppose wallet address 123456789abcdef123456789abcdefis a made up wallet address for Richie.

I want to be able to run

./client -save 123456789abcdef123456789abcdef -as Richie

So I can run

./client -send 1000 -to Richie

or

./client -send 1000 -to 123456789abcdef123456789abcdef

And they will both do the same thing.

Suggestion is to create a JSON file called addressbook that stores key:value pairs of name:wallet address. Running a contract command should first check to see if the string is a key in the addressbook, and if it is, use the value.
