Several Corrections & Clarifications Suggested On IRC

Browse source 
**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.

### Remote Procedure Calls (RPCs)
**Warning:** the block chain and memory pool can include arbitrary data
which several of the commands below will return in hex format. If you
convert this data to another format in an executable context, it could
be used in an exploit. For example, displaying an output script as
ASCII text in a webpage could add arbitrary Javascript to that page and
create a cross-site scripting (XSS) exploit. To avoid problems, please
treat block chain and memory pool data as an arbitrary input from an
untrusted source.
