Xcode 6 upgrade checks to project & schemes

Xcode touched the project files.  Opened in Xcode 6.0.1
Apple docs for best-practice app termination
Some docs based on empirical evidence
Use UIApplication private API and delegate to quit gracefully

This ensures that UIApplicationDelegate methods:

* applicationWillResignActive:
* applicationWillTerminate:

are called and the app will exit with success.
Allow the http payload to control exit behavior

* applicationWillResignActive: might need longer times for some
  app that cache a lot of data.

* controling the exit code is essential for code coverage.
No modules on library targets; imports Metal

Xcode 5.1.1 users are reporting problems when calabash.framework
is built with Xcode 6*.

Modules are _required_ with Xcode 6 for dylibs.

The calabash.framework and frank library do not need to use
modules, so we should turn them off.
