cabal-1.6.0.0

[Duncan Coutts]

I've tagged Cabal-1.6.0.0 and the tarball is on the cabal website. 
http://haskell.org/cabal/download.html

Tomorrow I'll update the version of Cabal that hackage is using and
upload Cabal-1.6.0.0 to hackage.

We're also planning to bump and upload the extralib packages tomorrow.

I also hope to release cabal-install-0.6.0 in the next couple days. In
the mean time please use the darcs version and report any issues.
