Add and document m_hideoper, used to hide oper status from non-opers.

Note: This module ONLY conceals numeric 313. Any other cloak-and-dagger
private eye stuff you want to do, like setting your host back to a non-
oper host, you must do yourself, this module wont mess with anything else
on your behalf.
