Just print sql commands which would normaly generate hibernate with ddl=update

[dunsun]

Would be very useful to be able to just print sql commands (without making any real changes to a production db schema) which hibernate produces if you have set jpa.ddl=update in your conf.

Then anyone could print these alter sql commands into a file and then would manually (check if all is ok) and copy/paste them into sql console.

Will try to implement this.
