Pull request description:
This is a rebased version of #60
Since Qt 5.5 there are [means](https://doc.qt.io/qt-5/qobject.html#Q_ENUM) to register an enum type with the meta-object system (such enum still lacks an ability to interact with [QSettings::setValue()](https://doc.qt.io/qt-5/qsettings.html#setValue) and [QSettings::value()](https://doc.qt.io/qt-5/qsettings.html#value) without defined stream operators).
In order to reduce global namespace polluting and to force strong type checking, this PR makes BitcoinUnits::Unit a scoped enum (typedef BitcoinUnits::Unit BitcoinUnit;).
No behavior change.

Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
- extend PaymentServer with setOptionsModel() and rework initNetManager()
to make use of that
- fix all other places in the code to use display unit from options and no
hard-coded unit
- try to enforce the same style to all Qt related files
- remove unneeded includes from the files
- add missing Q_OBJECT, QT_BEGIN_NAMESPACE / QT_END_NAMESPACE
- prepares for a pull-req to include Qt5 compatibility
