Provide list{addresses,aliases,users,relocated} subcommands The patch provides the list{addresses,aliases,users,relocated} subcommands to the UI. All commands actually take the same path in the code and only one query is run with different parameters for each case. There are still two shortcomings: 1. With alias domains, the output order is not as one might want it, e.g. foo@example.org bar@example.org foo@example.com bar@example.com when it should really be foo@ twice and then bar@ twice. I have not found a way to modify the SQL accordingly. 2. The SELECT queries for Accounts, Alias and Relocated are hard-coded in common.py.
