After some dirty grepping, regexing and perling, I present to you: internal links!

I wish there was a way to make this more robust, these will only work on the html version,
and assume we don't change filenames...

To mimic github flavored markdown for local viewing.
Note that this requires a development version of jekyll.

with_toc_data was updated in vmg/redcarpet#186
to generate pretty ID attributes for Hn headers, which is what we use
for cross-linking

Add chapter number to YAML, which is replace in numbering.css.
Use CSS counters for chapters, sections, subsections | examples.
Examples are detected by looking at the H3 element's id,
which redcarpet derives from the heading's title.
It must start with "Example:", and the whole title is suppressed
by a little javascript, so we can make Examples look like in the pdf.

For example, `### Example:` becomes `Example 3.2.10`,
if it's the 10th example in Section 3.2.

To avoid confusion, removing artifacts for
currently unsupported targets (pdf/single-page html).

I'd like to bring those back, but in the mean time let's avoid distractions.

Add Travis build.

The bulk of the effort was done in:
https://github.com/iainmcgin/scala-ref-markdown/

I just ported it to redcarpet 3.1, added a jekyll build to run on Travis,
and fixed some long-standing spec bugs.

As described in spec/README.md, for now we're only generating
an html page per each chapter with a rudimentary toc index.
We'll focus on presenting this more nicely first, and then
look into a pdf / single-page html version.
