Binary install

#### Changes

- I added the possibility to install from the official binary packages.
- Then I added uninstall recipes for package, source, and binary install strategies.
- Added tests for the binary install recipe

The above is all tested on Ubuntu 12.04, and works fine with Monit 5.8.1.

Hope this helps, and thanks for an awesome cookbook! :+1: 

#### Issues

I tried to fix the tests, but they keep failing on CentOS in the source install recipe. (that was failing before my fixes). Unfortunately I don't have time to dive deeper into that now, mostly because we don't run on CentOS here.. Maybe someone else would care to have a look at it? I'd be happy to help out later.
