Warning when Sheet Trim Settings are set to zero

For some jobs, trim=zero is useful. However, on most particle panel cuting (I think, this is a large usage), trim zero is never used. For example, I use at least 10mm on all sides. So, I recently used on some specific job a zero trim settings, then I forgot to restore to normal. So I messed up a job quite costly.

My feature request should be a message issued "Sheet Trim Settings are set to zero. Are you sure you want to continue?" just before Optimizing.

I think this will save alot of money for all of us :)

Thanks!
