#63 Restrict certain doctypes, topics, events, authors per group

[Eric Vaandering]

Restrict certain doctypes, topics, events, authors
based on the logged in group(s).

Restrict can mean:

Forbid using
Forbid seeing that such is used
Require extra effort to assign.
Forbid do any of this by default (for all groups & public)

Version 8.0 adds a table Suppress with two fields for
view and modify to be able to accomplish this
