They were temporary additions to ease the transition.

Having these inside functions is silly and redundant now.

Step two in abstracting away boost::filesystem.

To repeat this, simply run:
```
git ls-files \*.cpp \*.h | xargs sed -i 's/boost::filesystem/fs/g'
```

This is step one in abstracting the use of boost::filesystem.

Minimum boost version was bumped to 1.47.0 in #8920, which
means the configure step won't even pass with older boost.

This version has boost filesystem v3, which means the
(crappy) fallbacks for older versions can go.

$ contrib/devtools/copyright_header.py update .

Generalize the clickable label functionality.

We will use this to add similar functionality to the sync icon.

None of these are very serious, and are leaks in objects that are
created at most one time.

In most cases this means properly using the QObject parent hierarchy,
except for BanTablePriv/PeerTablePriv which are not QObject,
so use a std::unique_ptr instead.

Allows multiple selection and action for the nodes in the peer and ban tables in the Debug Window.

Generate an (invalid) example address for in the bitcoin address
widgets, based on the network prefix, instead of hardcoding a mainnet
address.

- `1NS17iag9jJgTHD1VXjvLCEnZuQ3rJDE9L` for mainnet (same as now)
- `n2wxQmfexkjwEPgdD6iJA7T7RtzkmHxhFc` for testnet

Service bit logic by Nicolas Dorier.

Only download blocks from witness peers after fork.

As a side effect, the qt user will see "test" instead of "testnet"

Also:
* Preserve white space
* Make fixed font as large as default font

-Move from .h to .cpp: in main, net and wallet
-Remove unnecessary #include "main.h"
-Cleanup some wallet files includes

- It is now allowed to disconnect peers from peers tab via
  right-click context menu. Peers are not permanently banned!

Stop translating the NODE_* names as they are technical and cannot be translated.

- creates a "Bitcoin (testnet).lnk" when on testnet or a "Bitcoin
  (regtest).lnk, when on regtest
- fixes #5778

The default font changed again.

The real fix is to compile qt against a >= 10.8 sdk, but this is simple enough
to backport to 0.10 to avoid having to do that there.

Note: NSAppKitVersionNumber is a double and there's no official value for
NSAppKitVersionNumber10_10. Since == isn't reliable for doubles, use Apple's
guidelines for testing versions here:
https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKit/

Chinese and Japanese fonts have been hard-coded as well, otherwise they fail to
show up at all.

SubstituteFonts() has been moved to after app identification so that QSettings
are accessible.
