* Remove the QR Code error corrections subsection.
* Remove the non-example Payment Protocol text from developer examples.
* Update reference links and autocrossrefs to reflect above deletions
* Fix CSS padding problems reported by @saivann
* Remove all HTML comments from autocrossref text to allow easy checking
for broken link definitions: find _site -name '*.html' | xargs grep '\]\['
* Add PNG versions of guide and example SVG icons. (optipng run)
* Add new Developer Examples page
* Add a transaction tutorial describing in detail how to make various
different transactions.
* Add a new "multicode" CSS class to allow combination of consecutive
code blocks into a single code block. This lets us use pygments
highlighting for multiple different types of code within the same
aparent block of code.
* Get autocrossref to ignore code blocks so we don't need to endcrossref
every time we encounter a code block. This makes the source much more
readable and maintainable.
Thanks also (in alphabetical order) to @cbeams, @mikehearn, and
