addSlash is semi-documented in the .txt docs dp wrote, see 
docs/txt/nevow-traversal.txt.

Basically, addSlash=True forces a redirect when a resource is requested 
without the trailing slash. addSlash serves two main purposes:

   * Relative URLs become manageable.
   * Directory-like resources can process the trailing '' segment and
     choose to render a listing or a default resource such as index.html.

Browsers append a slash when requesting the root resource of a site so 
it makes sense for root resources to be addSlash=True.

Yes.

Yes, but probably not too much ... although dp might have different 
ideas about that.

Subsribe to the nevow commits list.

I'll let dp answer this more but I think that branch is about finalising 
the livepage API. The old API had a few problems, especially around 
error handling.
