The change also includes a new MultiSettings feature that allows
settings keys common to all configurations. The splash screen disable
is the first of those to be used.
The MultiSettings class has been made safer to use by ensuring it
saves and re-enables the current QSettings group when doing multi
settings actions. This allows access to common, across configuration,
items while within a normal settings group without breaking the
MultiSettings internal implementation.
