Andrej Stieben db949bb802 Updated modules to allow for partial overrides without errors 
Only define functions if they have not been defined before, e.g. in themes. This makes it possible to override parts of a module and still use the other functions.

// This is a purely experimental module and is not yet generally useful.
// The eventual goal is to provide a json backend to fetch content and fill the current page.
// The page will be filled in on the frontend using javascript.
// At the present time this page is based on "network", but the hope is to extend to serving
// any content (wall, community, search, etc.).
// All search parameters, etc. will be managed in javascript and sent as request params.
// Security will be managed on the backend.
// There is no "pagination query", but we will manage the "current page" on the client
// and provide a link to fetch the next page - until there are no pages left to fetch.
// With the exception of complex tag and text searches, this prototype is incredibly
// fast - e.g. one or two milliseconds to fetch parent items for the current content,
// and 10-20 milliseconds to fetch all the child items.
