term: add term_damage_cursor() and term_damage_margins()

Browse source 
term_damage_cursor() damages the cell where the cursor is currently
at. This can be used to ensure the cursor is re-drawn, if there aren’t
any other pending updates.

term_damage_margins() requests the margins be redrawn the next time we
render the grid.
