Introduce --private/ -p distinct from --app/ -a

Private mode gets a particular window title, always defaults
to reading the default config folder but never saves data.

App mode applies a custom window layout with no toolbars
and using the page icon as the window icon.

From now on private and app are independant modes, so apps
can save data if config is given. Both can also be combined.
