wallet: add freeze/thaw/frozen commands
These commands let one freeze outputs by key image, so they do not appear in balance, nor are considered when creating a transaction, etc This is helpful when receiving an output from a suspected spy, who might try to track your other outputs by seeing with what other outputs it gets spent. The frozen command may be used without parameters to list all currently frozen outputs.
