Class to wrap QSettings.
* Exposes all the methods of QSettings.
* Adds functionality for OpenLP Portable. If the ``defaultFormat`` is set to
``IniFormat``, and the path to the Ini file is set using ``set_filename``,
then the Settings constructor (without any arguments) will create a Settings
object for accessing settings stored in that Ini file.
``__default_settings__``
This dict contains all core settings with their default values.
``__obsolete_settings__``
Each entry is structured in the following way::
('general/enable slide loop', 'advanced/slide limits', [(SlideLimits.Wrap, True), (SlideLimits.End, False)])
The first entry is the *old key*; it will be removed.
The second entry is the *new key*; we will add it to the config. If this is just an empty string, we just remove
the old key. The last entry is a list containing two-pair tuples. If the list is empty, no conversion is made.
If the first value is callable i.e. a function, the function will be called with the old setting's value.
Otherwise each pair describes how to convert the old setting's value::
(SlideLimits.Wrap, True)
This means, that if the value of ``general/enable slide loop`` is equal (``==``) ``True`` then we set
``advanced/slide limits`` to ``SlideLimits.Wrap``. **NOTE**, this means that the rules have to cover all cases!
So, if the type of the old value is bool, then there must be two rules.
