Permit site-wide static pages

[asmecher]

Currently static pages must be associated with a specific context. Permit site-wide (context_id=0) static pages, and ensure that they can be administered through the Site Administrator's tools.

This would probably benefit from pkp/pkp-lib#1923

Is there any chance that this issue will be scheduled for OJS 3.1.1? We are impatiently awaiting it for one of our multi-journal installations.

@CFanselow, I think this plugin is going to be deprecated in favour of the custom nav menus toolkit, which is already included in OJS 3.1.x. I believe that tool already includes support for site-wide custom items. @defstat maintains this code and can fill you in on the details.

@asmecher
You are are right! That's a great toolkit, thanks a lot!!!
