ludic.ui: an unmounted component is mounted again rather than made again - its record renewed (a generated renew), its props and model kept; an action's call answers into a ring

A prompt that comes and goes as a player walks (co-op's netleak: in_get, cmp_*_new, bd_class, value_slot/put)
made a new record, props and model on every mount, and an action's call answered into a new Val (ev_call_with).
examples/library/ui_remount: two thousand comings and goings hold the heap at 0, and the counter starts at 0.
