Various performance tweaks to CCoinsView

* Pass txid's to CCoinsView functions by reference instead of by value
* Add a method to swap CCoins, and use it in some places to avoid a
  allocating copy + destruct.
* Optimize CCoinsViewCache::FetchCoins to do only a single search
  through the backing map.
Native versions for AllocateFileRange()
Drop padding in blk* when finalizing file
translations update (bitcoinstrings.cpp + bitcoin_en.ts)
Do not use C++11 std::vector.data()

std::vector.data() is a C++11 feature that makes my OSX build machine unhappy.
Use QImage.bits instead of QImage.constBits to ease backporting

Image.constBits was introduced in Qt 4.7.  Should be ok here to use
QImage.bits which allows linking against the Qt in Squeeze.

[build] installer: first innoSetup installer script.

 - provides a simple way for endusers to register terracoin: URI handler.
Reimplement click-to-pay links. Add OSX support.

Switch to using Qt's QLocalServer/QLocalSocket to handle bitcoin
payment links (bitcoin:... URIs)

Reason for switch: the boost::interprocess mechanism seemed flaky,
and doesn't mesh as well with "The Qt Way"

qtipcserver.cpp/h is replaced by paymentserver.cpp/h

Click-to-pay now also works on OSX, with a custom Info.plist
that registers Bitcoin-Qt as a handler for bitcoin: URLs and
an event listener on the main QApplication that handles
QFileOpenEvents (Qt translates 'url clicked' AppleEvents into
QFileOpenEvents automagically).
[tests] fix: CTerracoinSecret data type.
[core] transaction,notifier: posted data now signed.

 - first http notification for a given transaction now include a new
   json document, providing message signature for the first json
   document.
 - json transaction data is signed using the existing signmessage()
   function (ECDSA), so any remote client may verify signature, without
   the need for extra keys/data.
 - https://github.com/terracoin/terracoin/wiki/TransactionNotifier
   should be updated soon.
[core] transaction,notifier,fix: missing closing bracket.
