Summary: array: move instead of redraw graphics

Initial Comment:
This is a patch that fixes slow ("sticky") displacing of arrays by moving instead of recreating their graphics.

It also fixes the problem of array name not appearing immediately after its creation as it was necessary now that arrays don't recreate but only move all that belongs to their appearance when displaced.

Message:
array moves should really use the tcl 'move' command.  It will greatly
speed things up, IMHO.  Right now, changes in arrays can generate up to 1
megabyte of Tcl code per second for the GUI to execute.  Using a move
command, we should be able to get that down to a much smaller amount, I
think three or four orders of magnitude is feasible.

That said, I have not tested this patch.

Message:
Interesting idea - I wonder though if it would be simpler and more
maintainable to use some sort of throttling instead.  Array moves are
definitely ugly now.
