sixel: improve handling of images when reflowing the grids

Browse source 
Update the sixels' 'row' attribute when re-flowing a grid, to ensure
it is rendered at the correct place.

This should work in most cases, but will break when the cell size has
changed (e.g. font size increase/decrease, or a DPI change).

This patch also moves the sixel image list from the terminal struct
into the grid struct. The sixels are per-grid after all.
