The CLI was very chatty about its operations, which made it unsuitable for use in scripts. In addition, it always exited with a success (0) status, even when operations failed. This change fixes both of those issues: 1. The cli doesn't output anything to stdout except when it retrieves a password successfully, in which case the password (alone) is output followed by a newline. 2. The cli doesn't output anything to stderr unless the -v (verbose) flag is specified, in which case it prints debugging info to stderr on all operations. 3. The cli exits with status 0 only for success; if an error is encountered it returns status 1. Fixes hwchen#130.
