Hammer

I'm not sure what I did to my last fork but I broke it very very much, so I re built it from scratch :)

This request is to introduce the hammer lib 
https://github.com/UpstandingHackers/hammer/blob/master/README.md

brew has been tested on mavericks with dependancies as is but their might be some other deps I missed. If they are missing though they can be added from home-brew since thats what I used to install the libs on my test machine that I used to test the build.

I have made all the changes requested in my original pull request by mikemcquaid. I am aware that homebrew will wait until the lib is at a release version as apposed to the RC it is currently at but this is the best way I know of to get feed back if there is anything else to be done.
