Get users doesn't display all user information

[MorganEPatch]

(h for help) : gu
(Optional) Username: 
(Optional) By metadata: 
(Optional) By project slug: 

username: root
active: True
display_name: root
email: None

username: patcht
active: True
display_name: Tristan Patch
email: [email protected]

The "get users" command displays the username, active, display_name, and email fields of the user object. This is missing the permissions fields (site_spectator, site_manager, site_admin, all booleans) and the meta field (which is just a string).

In particular, it would be nice if the permissions fields were condensed into one field for display, permissions, which could be a list of the permissions a user has. This is the same way that permissions are displayed for projects, as below:

(h for help) : gp
(Optional) (y/N) Allow revised?: 
(Optional) (y/N) Allow deleted?: 
(Optional) By project slug: test

slugs: test, test1
name: Test Project
users: 
    kennric <member, manager, spectator>
    patcht  <member, spectator>

So, we could display users as, e.g.:

username: patcht
active: True
display_name: Tristan Patch
email: [email protected]
permissions: <spectator>
meta: 'OSL Student Developer'

username: kennric
active: True
display_name: Ken Lett
email: [email protected]
permissions: <spectator, manager>
meta: 'OSL Lead Developer'

username: Ramereth
active: True
display_name: Lance Albertson
email: [email protected]
permissions: spectator, manager, admin>
meta: 'OSL Director'
