Add static and inline to getter in all qPref header files
Remove call to GET_PREFERENCE_* in qPrefDisplay.cpp
Remove GET_PREFERENCE_* from qPrefPrivate.h
static inline is slightly faster than a function call, but it saves
a lot of coding lines (no lines in qPref*.cpp). Getters are a direct
reference to struct preferences, so they will normally only be used
from QML.

Add qPrefPrivate class which contains one QSettings variable,
delete QSettings from qPref* class definitions
this secures there are only instance of QSettings
(QSettings needs to be in a QObject class to work)

Update set/get functions to follow common name scheme:
- get function have same name as in struct preferences
- set function have set_<name in struct preferences>
- signal function have <name in struct preferences>_changed
one class one .h/.cpp is the C++ idiom. Having load/sync of each
variable in 1 functions (in contrast to the distributed way SettingsObjectWrapper
handles it) secures the same storage name is used. Having the set/get/load/sync
functions grouped together makes it easier to get an overview.
