Patch to read package-specific cabal-install config

[Erik Hesselink]

Hi Carl,

That's right, upload to multiple repo's doesn't work at all, for
multiple reasons. The advantage of multiple remote-repo's is that
cabal-install pulls from all repo's when installing a package. So you
can have packages depend on both private packages, and packages from
the public hackage, and install them with a simple 'cabal install'.

For upload, we've written a simple command line utility. I can share
part of the code, if you want. Or you can just use the web interface
to upload to your private hackage.

I think the 'right' solution for cabal upload and multiple remote
repo's is to have sections in the cabal file, and have fields like
username and password belong to a remote repo section. The upload
command then probably needs a flag to indicate to which remote repo
you want to upload.
