Settings menu access

[amandafrench]

On multisite installs it seems wise to offer the option of limiting access to the Participad Settings to the network admins instead of giving it to the site admins. I hard-coded this change on thatcamp.org (see chnm/thatcamp-org@a76efa8), but it might be good to offer it as an option.

I should add that of course Network admins on multi-site installs can choose globally whether to let site admins activate / deactivate / manage plugins that aren't Must-use or Network Activated; on thatcamp.org they can. Except, now, for Participad.

This is a good suggestion. I'll put in a filter right away. A UI option takes much more time to implement - maybe at a later date.

To implement, put the following in an mu-plugin:

add_filter( 'participad_hide_admin_panel_from_site_admins', '__return_true' );

I'll leave the ticket open in case we want to do a UI option at some point.
