groovy template had some errors for html/txt report when it has git changes, I didn't check for svn/cvs

Following varible doesn't recognize inside groovy

• cs.hudsonUser (no husdonUser for changeSet class, it just error instead of return nil)
• cs.changeNumber (does it work for cvs or svn ?)

Since I don't know the background and other environment (cvs/svn), I can't provide complete patch
