Small docs corrections

[21:48:14] <md2k7> feel free to make it MIT if you like

Keeps the "windows", "windowsxp", "windowsvista" styles.

Reduces the size of a static bitcoin-qt.exe by ~400 kB.

Bugfix: Move boost::interprocess Win32 workaround to Bitcoin-Qt sources, rather than hacking boost in gitian

Replace all occurances of license.txt with COPYING, including naming the file COPYING.txt on Windows

That patch has been broken for a long, long time (forever?) and
doesn't make sense.

* Updates package description to note that blockchain now takes
  2+ GB instead of 150+ MB.

* Stop creating DB_CONFIG with DB_LOG_AUTO_REMOVE as that is set
  in Bitcoin itself now.

* Update changelog with 0.6.2 and the current updates.

All client version information is moved to version.cpp, which optionally
(-DHAVE_BUILD_INFO) includes build.h. build.h is automatically generated
on supporting platforms via contrib/genbuild.sh, using git describe.

The git export-subst attribute is used to put the commit id statically
in version.cpp inside generated archives, and this value is used if no
build.h is present.

The gitian descriptors are modified to use git archive instead of a
copy, to create the src/ directory in the output. This way,
src/src/version.cpp will contain the static commit id. To prevent
gitian builds from getting the "-dirty" marker in their git-describe
generated identifiers, no touching of files or running sed on the
makefile is performed anymore. This does not seem to influence
determinism.

It could just as well be on either part of the gitian build, but to safely put it on the Qt side would require bumping the filename, and every gitian user rebuilding it.
v0.5.3.1 put it on the Bitcoin side, and this is easier to work with and keep safe, so I'm moving it.

Use `qmake MINGW_THREAD_BUGFIX=0` to disable

- icon from the LGPL Nuvola set (like the tick) - http://www.icon-king.com/projects/nuvola/
- include 'boost/version.hpp' in db.cpp so that the overwrite version of copy can be used
- catch exceptions in BackupWallet (e.g. filesystem_error thrown when trying to overwrite without the overwrite flag set)
- include db.h in walletmodel.cpp for BackupWallet function
- updated doc/assets-attribution.txt and contrib/debian/copyright with copyright info for new icon

Mac deploy tool: make dylibs writeable when copying into app bundle, so they can be stripped/nametool'ed

* My patch for miniupnpc has made it into the latest MacPorts release: https://trac.macports.org/ticket/31354
* Documentation has been changed appropriately
* New pure-Python macdeployqt; leverages all problems with the stock macdeployqt

These should never have been there, bitcoin isnt anonymous without
a ton of work that virtually no users will ever be willing and
capable of doing.
