Make it possible to set a non-default wxPersistenceManager to use and allow
overriding of GetConfig() and GetKey() methods by making them virtual and
documenting them.
This can be notably used to allow porting of the existing code to use
wxPersistenceManager while keeping compatibility with the old settings.

In practice names are not often used so typically whenever you want to make a
window settings persistent you also need to set its name and the it's
convenient to let a single function do both tasks, so add an overload taking
the name string (this is a separate function instead of optional parameter to
avoid compilation errors if this is ever used with non-wxWindow-derived
objects which don't have SetName() method).
Also expand the documentation slightly and add @since tags.
