Add -walletnotify to call an external script on wallet transactions
Add timeoffset to getinfo RPC call

Provides a method to get the difference between network adjusted time
and local time from the RPC interface.
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
Fix getbalance discrepency

Two changes:

Use IsConfirmed() instead of IsFinal(), so 'getbalance "*" 0' uses the same
'is this output spendable' criteria as 'getbalance'. Fixes issue #172.

And a tiny refactor to CWallet::GetBalance() (redundant call to IsFinal -- IsConfirmed
calls IsFinal).
getbalance with no arguments and 'getbalance "*" 0' could return different different results,
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.

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).
Enable dumpprivkey in safe mode
Pass compiler flags down into leveldb make

Fixes issue#2288. Includes cleanups from Luke's pull 2243.
Minor build fixes

Two changes: make some linux-specific linker options linux and linker specific.
And in the cross-compile environment, prefer the $HOME/qt/bin tools to
whatever might be somewhere else in the path.
Change progress bar from block-based to time-based

This is less confusing to most people, and doesn't rely on estimates
of the total number of blocks received from other nodes.
