Merge pull request #116 from Bengt/code_block_closing_fences

Add example from issue #94 about indented code block closing fences
Tweaked the closing fence section added in last commit.
Add EMPHASIS_STACK_LIMIT.

If we get more than 1000 deep in potential emphasis/strong emphasis
openers, we refuse to add more to the stack.  This prevents the
sort of stack overflow we previously got with

     python -c 'print "*a **a " * 100000; print " a** a*" * 100000' | ./cmark

Partially addresses #166.
Moved TODO item to tracker
Require space before closing # sequence in ATX header.

Closes #169.
Removed narrative.md, moved its content to README.md.
Put multiple versions of spec on website.
Add title to list of versions at spec.
spec2md.pl:  Make Example numbers into links.
Have index.html on web page redirect to latest version.
Added clear and permalink to dingus.

Serve dingus from dingus.html.

Add redirect page as index.html.
Dingus improvements; moved to top level.
Added (interact) links to spec, to open examples in dingus.
dingus:  Show HTML tab if query has text.

This should be a safer default; if someone sends you dangerous HTML,
you'll see it immediately.
Updated spec date/version.
Makefile: Make sure we update redirect on every new version of spec.
Landing page for spec is now a list with links to all versions.
