Open URL in default browser instead of Safari

This exchanges the script executed when opening the podspec. Instead of opening Safari with `tell application "Safari" to open location "{query}"` it's just `open location "{query}"` to open it in a default browser.

I just unzipped the `.alfredworkflow`changed the line and zipped and renamed it again. I don't know if this is the correct way of doing it. So I highly recommend it to be tested by someone else first.
