Fix mispelled 'namespace'
root_page for paginator should default to paginator namespace.

Fixes #122
Normalize paginator URL format to always omit trailing slash.
Opt in to paginator root_page. If not set, don't use it.
Serve/compile paginator page #1 at <namespace>/1 if not root_page not set.

If root_page is set assume it gets compiled elsewhere.
Improve compile output messages.
Add ability to disable paginator compile if not using.

This avoids a compile error if the paginator.html layout is not found.
Small style change to compile output.
