grab "hawk" on hackage

[gelisam]

this project is currently "haskell-awk" on hackage in order to avoid conflicting with the "Hawk" project on hackage, a Web Application Kit. However, today, more people care about this project than about that Web Application Kit, so it would make sense to try to grab the "hawk" namespace. It turns out that hackage is case-sensitive, so we can do it without shedding any blood!
