'/search' endpoint broken

[pacMakaveli]

Hey,

It looks like the '/search' endpoint is broken and instead of requesting http://giantbomb.com/api/search? it goes to http://giantbomb.com/search which in turn returns HTML instead of JSON.

I managed to fix this with:

    def end_point
      GiantBombApi::Client::API_URL + 'search'
    end

I wanted to make a pull request but I'm not sure this is the proper way to fix this. Maybe we need to understand why GiantBombApi::Request::Search doesn't use API_URL when making a request instead of hardcoding the full URL in the class.

I tried to have a look through the code but to be honest it's a bit complicated for me and I don't really have the time to properly learn how it works.

Thanks
