Report crashes encountered during CI runs as part of the test result

It would be great if we could report crashes that happen during CI runs as part of the automation results.

For Simulator:
App crashes will be generated within /Library/Logs/DiagnosticReports/. Also, the output from "/Library/Logs/iOS Simulator//system.log" (7.x) or "/var/log/system.log" (6.x) sometimes contains a more interesting stack trace after symbolicating. It generally comes directly after "Terminating app due to uncaught exception".

For Devices:
If Xcode can pull logs and crash files off of devices, I'd assume the same should be possible from command line (maybe requires using libimobiledevice). I haven't tried this before, but I'd hope this could be possible.
