Security: Fix privilege escalation with crafted /trn

This fixes a bug that allows any user with `forcerenameto` permission
(which by default includes the entire ~ group) to escalate to console
permissions, which is much more powerful.

Suppose user "Jasmine" has the ~ group, but not console permissions and
suppose user "Zarel" is on the console list on config.js. Jasmine could
escalate to console permissions with these commands:

    /frt Jasmine, Zarel
    /trn Zarel

The use of the /trn command sets her User object's `forceRenamed`
property to false, allowing the console userid check to pass.

This bug meant that the attack surface area to completely take over the
sim server was as large as the ~ group, not just the list of console
users. This commit fixes the bug by correctly propagating the
`forceRenamed` property when using /trn.
