Improved Bot Detection

[joshuasiler]

Dramatically improved bot detection capabilities. Added rake test. Fixed some crashy bugs with nil values in some user_agents. Incremented gem version.

Thanks for the improvements. Before I can merge this in, a few things need to be changed:

• Remove the komodo file, as that is unique to your environment
• Revert the change to Rakefile, since I wish to keep the bundler gem tasks (more specifically, find a way to include your new task as a lib/tasks/.rake file if possible)

Please submit a new pull request once you've made the improvements above. I will have to manually merge since I've already merged in another pull request, but the change is quite minor.

I appreciate the contribution!

Removed. Also cleaned up rake tasks as requested

Nice one, will give this a try. Will see if this improves things for Issue #3

It's going to need a bit of a refactor to get any better. Right now it's only looking in parsed "comments" part of the string, which doesn't exist in all cases.

Great job! Let me review the changes, make a few minor changes for consistency, and merge it in. Thanks guys.
