Derby site documentation cruft

[Kristian Waagan]

 Hello,

We have old cruft lying around in the directory structure for our website.
Unless I get push-back, I will delete the following directories:
10.0-bak
10.1_old
10.4_old
10.6_old
dev_original

I would also like to delete the following files, unless someone know 
that they are being used for something:
docs-10.0.tar
docs-10.0.tar.gz
docs-10.0.zip


In addition, the documentation for 10.6 is missing the write permission 
for the group.
Lily, can you please fix that?


Thanks,
--
