download no longer works

[shazron]

ios-deploy --download --bundle_id <bundle_id> --id <device_id> --to ./foo

See #153. AFCFileInfoOpen now returns non-zero (code 12).

At a minimum we need to verify what is not working and update our examples.

I'm investigating a problem where one version of my .ipa will not download any content, showing no error message at all (the bundle is found but the download will not occur). Other version of the same app (different archive/distribution processes) --download will work perfectly. Just sharing the scenario...
