Incompatibility with Rails 3.0

Hey Peek team,

I tried to install Peek into my org's Rails 3.0 app, and while installing the gem went fine, Rails got hung up on an error when trying to start the server up.

Some stack trace:

Seems that isolate_namespace isn't available in Rails::Engine before 3.1. 😢 Should the gemspec be updated to reflect this (since you list rails >= 3.0.0 there)?
