Title: Hide stack frames from raven.js

normalizeFrame() no not only hides stack frames from raven.min.js, but also from raven.js. This is useful if the uncompressed script is used in a development environment.

The parenthesis in the regex make me think that the original author intended to have the `.min` part optional.
