Use Terms "Pubkey Script" And "Signature Script"

Browse source 
This modifies commits provided by @petertodd to use the terms "pubkey
script" and "signature script" instead of other terms.

* Rename "scriptPubKey" and "output script" to "pubkey script"
  (suggested by @luke-jr). We leave a token "scriptPubKey" at the point
  where we define pubkey script so that searchers can find it.

* Rename "scriptSig" to "signature script" (suggested by @luke-jr). We
  also leave a token "scriptSig" at this definition point.

* Rename "redeemScript" to "redeem script"

* Defined ECDSA on secp256k1 curve as the crypto used in the Transaction
  section and added references to secp256k1 private/public keys and
  signatures.

* Removed "The Parts Of A Transaction" illustration by commenting it out
  in the HTML. Shoehorning the pubkey/signature script terms into this
  image was becoming difficult, and I'm not very fond of that
  illustration anyway. I'll see if I can think of a nicer replacement
  illustration for some point in the future.

* Add a short paraphrased version @petertodd's description of scripts as
  generalized crypto.

* Updated all the illustrations which referred to either pubkey scripts
  or signature scripts to use these terms.
