sv list file support, refactoring begins #2033

Separated out node logic from general logic in forms, defaults.  Still working on render.

Began supporting files.

Separation of logic includes using plugins for various areas of the sv list.  Began on the node_biblio plugin, since that is probably the most demanding.  Plugin system is cool.  Node plugins load on all LOP forms, but not on LOF.  But during render, only plugins for the current bundle are loaded.  Right now all the biblio plugin does is modify the form, but the same logic will be present during box render.
Fixed file urls #2033

Yes, there is file specific code in the generic sv list class.  But I wanted it to be able to default to using display_title when no other display function is provided.  That means I needed to implement display_title here.  Maybe the files class should override it instead?
Moved sv list classes into own files #2033
Add missing "ed." suffix for editor.
