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.
translations update (bitcoinstrings.cpp + bitcoin_en.ts)
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.

Internal RNG for approximateBestSubset to prevent degenerate behavior.

This fixes test_bitcoin failures on openbsd reported by dhill on IRC.

  On some systems rand() is a simple LCG over 2^31 and so it produces
an even-odd sequence.  ApproximateBestSubset was only using the least
significant bit and so every run of the iterative solver would be the
same for some inputs, resulting in some pretty dumb decisions.

Using something other than the least significant bit would paper over
the issue but who knows what other way a system's rand() might get us
here.  Instead we use an internal RNG with a period of something like
2^60 which is well behaved.  This also makes it possible to make the
selection deterministic for the tests, if we wanted to implement that.

Set CC/CXX properly for gitian build
reformat OS X build instrcs, add 10.8 + Homebrew

* reformatted the entire document to look pretty in both standard text and
  Markdown
* incorporated [my OS X 10.8 build instructions with Homebrew as the package
  manager](http://bitcoin.stackexchange.com/questions/3672/trouble-compiling-bitcoind-on-osx-with-homebrew/5253#5253)
* incorporated @gavinandresen's MacPorts and release build instructions based on
  an earlier revision of this commit
* added makefile patch necessary for Homebrew compilation to `contrib`
small changes in init, main, checkpoints.h and bitcoin-qt.pro

- remove an unneeded MODAL flag, as MSG_ERROR sets MODAL
- re-order an if-clause in main to have bool checks before a function call
- fix some log messages that used wrong function names
- make a log message use a correct ellipsis
- remove some unneded spaces, brackets and line-breaks
- fix style for adding files in the Qt project
