When used with --svn-repository option, ZopeProject should do a checkout after import

[Tiberiu Ichim]

The --svn-repository option creates the false impression that the generated project with be ready to run, integrated with svn. But that's not true, one needs to checkout the generated project manually. This might cause problems with more inexperienced developers starting with Z3.

The smallest change would be to add a message explaining how to do the checkout. Probably more elegant would be to do the svn import then erase the generated folder and do a full svn checkout, to have the project ready for svn integration.
