When moving by long distances (whole screenfuls) via API setCenter calls, reinitialize the grid. This solves an 'infinite loop' like problem where if you jumped by a long way, where addColumn/addRow were simply looping for so long that the browser went unresponsive/broken. Fixes issue reported by NickH on users list as well.
