lua: Implement wesnoth.view_locked() and wesnoth.lock_view()

Browse source 
Both are simple wrappers for display::view_locked() and
display::set_view_locked(), respectively. view_locked() returns a
boolean specifying whether the view is locked, and lock_view() takes a
boolean specifying whether to lock the view (true) or unlock it (false).
