The debugger can now correctly break on exceptions and show the corresponding line in the inspector. It correctly understands which scripts are internal to sky and does not pause during them. There is still a ton to make work here (including stacktraces which I have not tested), but basic functionality seems to work. The current implementation is not smart enough to unpause the inspector when the frontend disconnects. BUG=434510,434513 R=abarth@chromium.org Review URL: https://codereview.chromium.org/727593004
