fix #75 by computing evolution during frameRender

instead of pre-computing the entire evolution during preFrameRender, it creates 60 ticks' worth of grid data at a time during the rendering process, deleting old data as it goes. This works with the current render process and should still work if the render process changes, as long as render threads don't become extremely de-synchronized (which would probably be an issue anyway)
