[Freeciv-Dev] (PR#3593) gui-sdl: toggling map options doesn't redraw map

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

In the SDL client, toggling a map option doesn't call
update_map_canvas_visible, so the canvas doesn't actually get redrawn.

Attached is a way to fix this (for map_grid_callback only; others should
be similar).  Note this requires the new flush code.
