Create convinence method for reading settings

This method avoids having to create a SettingsInterface object that will
be only used to read a small number of settings before being destroyed.
It creates a static object that persists between invocations. Through
the use of QSettings for reading a value, we are assured of always
reading the most up to date version of settings as this class guaranties
that changes done to one QSettings object will be immediately visible in
other QSettings objects.
