Refactor page rendering into a separate function 

Refactoring page rendering so that we can fix the performance issues
with editing drafts. The plan is to defer the refresh cycle if all the
changes are to draft tiddlers.

We need to do a bit more of this to get startup.js into better shape
(and more extensible).
