Title: stack frames from vendored bundler gems appear as "Application Frames"

I typically install bundled gems in vendor/bundle, unfortunately this causes all of the bundled gem sources to appear as "Application Frames" in stack traces. Here is a fix: it checks if Bundler is being used and if it is, then marks ErrorFrames whose filename is in the bundle_path as :bundled.
