Title: Fix the environment for Ruby 1.8.7 through 1.9.3

I couldn't figure out which Ruby version this gem was targeting. It depends on RCov, which doesn't work on `1.9`, but the tests use the `Object.new\n.inspect` syntax which doesn't work on `1.8`. So I fixed it. All tests now pass on Ruby `1.8.7` through `1.9.3`, and this works out of the box on each version:

```bash
$ git clone git://github.com/adammck/health_graph.git
$ cd health_graph
$ bundle install
$ rake test
```

This also removes the hard-coded versions on the dependencies, like @aub's #6, because those were way out of date, and not necessary.

I left the commits as-is, but I'm happy to rebase them if that would be preferable.
