Bug 9571 [Alternate] Fix width for textareas in Edit Item screen

This alternative patch modifies the script where the input markup is
built and adds an alternative configuration for textareas. This gives
the textareas explicit "cols" and "rows" attributes. I think this
solution is preferable to a style fix because it solves the bug while
eliminating some invalid markup (no "size" or "maxlength" attributes on
textareas, which are invalid without explicit dimensions).

To test, add a nice big chunk of text to an existing item's item field
like "Public note" (952$z), save, and edit again. The field should now
be displayed in a more comfortably-sized textarea.
