bpo-38022: IDLE: upgrade help.html to sphinx 2.x HTML5 output (GH-15664)
The HTML5 output from Sphinx 2.x adds '<p>' tags within list elements. Using a new prevtag attribute, ignore these instead of emitting unwanted '\n\n'.
Also stop looking for 'first' classes on tags (no longer present) and fix the bug of double-spacing instead of single spacing after <pre> blocks.
