Hyperlink

Prototype code for hyperlink support.

Right now it needs to create a global _pages variable to work, for the objectExists() method to tell if there's a page or not for a given value like "dijit/Dialog".

It's also generating HTML links from javascript, based on a baseUrl variable that should be configurable, rather than hardcoded to "/".

And also, it only processes the page level summaries.   That's just to prove that it's working.  hyperlink() or autoHyperlink() should eventually be called on summaries, descriptions, return-descriptions, parameter types, property types, return types, "from module", and lists of superclasses.   (Maybe some other stuff too that I forgot.)

Didn't mean to include the lint changes in this pull request, but added them by accident.
