Updated DAO code generation as discussed over the email

This should be a complete implementation of DAO generation according to the design we have discussed over the email. I've tested this on our project so the DAOs should be good to go, but of course a more diverse testing would be needed before releasing it to public. I'm open for recommendations and suggestions, so I see this as the first draft. Below is a list of files and comments. Contact me at kalinovsky@yahoo.com.

src/java/org/hibernate/tool/hbm2x
DAONewExporter.java This class is coded mainly to accept additional parameters such as dao package name and provide flexible
file naming that is used by Ant task. It would not be needed if I integrate my changes into GenericExporter.
