* 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.
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
* Correct misinformation about the dust limit. Reported by @dbilitch and
confirmed by @gmaxwell. Thanks!
* Drop reported minimum relay fee from 10,000 to 1,000 satoshis.
**Suggested by @cbeams:**
_includes/ref_block_chain.md:
* Mention that coinbase is the first transaction in a block.
**Suggested by @gmaxwell:**
_includes/ref_core_rpcs-abcdefg.md:
* Mention that you need to unlock your wallet when you run out of
keys in the keypool.
* Remove erroneous assertion that txindex=1 would allow
`getreceivedbyaddress` to check balances of addresses not
belonging to this wallet.
_includes/ref_transactions.md:
* Clarify that OP_RETURN scripts aren't usually executed because
they always return false.
en/developer-reference.md
* Add a warning about using block chain or mempool data in
executable context.
* update to modern, supported Ruby 2.0 version
* update gems to current versions using Bundler
* make jekyll configs confirm to current version
* switch deb package dependencies to cross-platform rvm
* ignore bundled dependencies
* some README mods as per @harding + @saivann
