heidisql cannot change grid to multi rows

HeidiSQL is a nice DataBASE sofware , always work well, but the recent versions cannot change grid to multi rows, but the early versions can for example HeidiSQL 12.8.0.6908

This is a new limitation, and fixes some issues with linebreaks in text content. See issue #2000

I just restored support for multi line grid rows, as the fixes for #2000 were mostly ineffective anyway. So the next build is again able to show you higher grid rows.
