manage_network_options is required for Network Settings
Switch formatting of array for longer list
If a user is a network admin, they should have all caps

We can pull them back at a later time if there are some we don't
want to provide at that level.
Tie activate_plugins and manage_network_plugins together
Only check the specific network for caps when one is passed

We only have one capability that checks the network ID at this point
Start getting granular with the network capabilities enabled
Use the new wsuwp_network meta key for a list of user sites
Add a wrapper wsuwp_is_network_admin for checking admin status
Adjust the logic showing the My Networks menu
Replace another super_admin check with wsuwp_is_network_admin
Don't show empty network menus under My Networks
Make sure super admins are set early

We may need to move this further up if possible
