upgrade to version 0.8

[Insurance Squared Inc.]

We're just wiping down a server to install nutch in more of a production 
environment.  Does anyone have any thoughts on whether we should upgrade 
to version 0.8, from version .7?  Our developer suggested that the only 
reason we would need to do that would be if we needed distributed 
computing; for the near future we'll be working off of one computer 
only.  So he's suggested we can stick to version 0.7.

Thanks.
