* Clarify a few places where payment request was used instead of
PaymentRequest.
* Clarify that payment isn't necessarily verified until the merchant
says so. Suggested by @saivann (thanks!)
* 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 icons for Developer Guide and Developer Examples so we don't
keep reusing the book icon.
* Update payment protocol links to point to developer examples when
appropriate.
Two unrelated minor additions which were requested at nearly the same
time.
* @mikehearn requested we add a link to @gavinandresen's PaymentRequest
generator. Added to _includes/guide_payment_processing.md with link
definition in _includes/references.md
* @Burrito-Bazooka requested we mention that the block reward halves
every 210,000 blocks. Added to _includes/ref_block_chain.md
Thanks also (in alphabetical order) to @cbeams, @mikehearn, and
@tgeller, among others.
