new cabal-get developments

[Isaac Jones]

Audrey Teng and I hacked on cabal-get a few weeks ago.  Some details
are here:
http://hackage.haskell.org/trac/hackage/ticket/62

Basically, Audrey was able to talk me out of my "smart server, dumb
clients" stance.  HackageDB is now just a directory tree with an index
file.  She also implemented better local install for mutiple cabal
packages with cabal-get.  I haven't played with this much.

The way it's going to work, at least for the short term, is that
anyone w/ access to monk.haskell.org (aka darcs) will be able to run
the 'put' program to add packages to hackage.

Anyway, take a look at the code and tell me what you think.  xerox is
going to be working on it for his SoC project, as we started to
outline here:
