jp9000 9f652e6416 Make settings window only save data that changes ...

Currently, if a user presses 'OK' or 'Apply' on the settings window, it
will save all data from all controls on a settings pane, regardless of
whether of not they were changed.  The major issue with this is that
setting the data will overwrite all default values, making it impossible
for default values to be used if a user didn't actually change a value.
(Thanks to palana for pointing this fact out)

So instead, mark a control as 'changed' using QObject::property() and
QObject::sender(), and add a few helper functions to controls to ensure
that they are checked to see whether they were actually changed directly
by the user before saving the value to the config.
