Add support for using an embedded .mobileprovision file

[kevinrenskers]

The xcrun command (used to sign an .ipa) can accept an --embed parameter, so you can use any .mobileprovision file instead of using the provisioning profile from the build setting in your project. This would be very handy in combination with the Cupertino gem.

You could add new devices to the profile, download the profile, create a build that uses that profile and upload to hockey. All from the command line.
