adding command for making grid bigger

[thomasrebele]

sometimes I select the wrong grid cell, so I wrote this small extension: pressing the key for the "enlarge" command makes the grid bigger again

Is this different from the "history-back" command? I don't actually use grid myself, but I enabled it in my keynavrc then used a grid, and the history-back command seemed to work fine (once I rebound it to not conflict with the keys that grid was using:]).

thanks, I had overlooked this command
