Title: specificed version of multi_json in gemspec

My app specified multi_json 1.1.0. Because bugsnag did not require multi_json at a specific version, I would get an error with MultiJson.dump

```
>> Bugsnag.notify(RuntimeError.new("Something broke"))
NoMethodError: undefined method `dump' for MultiJson:Module
from /Users/jon/.rvm/gems/ree-1.8.7-2012.02/gems/bugsnag-1.1.1/lib/bugsnag/notification.rb:83:in `deliver'
from /Users/jon/.rvm/gems/ree-1.8.7-2012.02/gems/bugsnag-1.1.1/lib/bugsnag.rb:33:in `notify'
from (irb):1
```

If I specificed multi_json at 1.3.6, the error worked fine.

MultiJson.dump was introduced at 1.3.4.
