moved templates folder in lib/assets
added basic getter for a page ready to paginate

This replaces a tiny part of the functionality that the old template
module had.
unbroke phantom wrapper tests
made toHtml retain the original section of the chunk it converts

This is because the paginator will need to retain the original section
of the page in order to keep track of the page numbers
rewriting paginator

- fixed it to fit in with the new formatter pattern, and the new html_page
module
- removed very very tightly coupled tests
- changed create-page phantom script to only return the page content
  rather than the entire page
Some tweaks

- updated to latest version of arg-err, fixing a commented out
  validation
- removed old dependency on the phantomjs module
