label: Add 'allow-select-on-focus' property

Browse Source 
Add an 'allow-select-on-focus' property to let the apps decide whether
it's desirable to select the whole text when a selectable GtkLabel grabs
focus. It is used in combination with GtkSettings:gtk-label-select-on-focus,
selecting the text only if both the app and the user allow it.
