[Settings] Added usage of settings variables in application.

The method is as follows:
**Add property to SettingsDataContext.
**Create a visual handler for the property in SettingsView.xaml.
**Modify App.config xml.
**Add updating of ViewModel property in ToggleSettings handler.
**Modify your affected ViewModel to handle the property.
**Use the property in its specific view.

Currently updates happen on toggling off the settings window.
