OS X `vendored_frameworks` should automatically get embedded appropriately.

[alloy]

This means that the framework should:

• Automatically get copied into the app bundle in the Frameworks dir.
• Automatically configure the application to load frameworks from the Frameworks dir, if they use @rpath.

Currently you have to do the following:

  s.osx.vendored_framework = "PLCrashReporter-1.2-rc2/Mac OS X Framework/CrashReporter.framework"
  s.osx.resource = "PLCrashReporter-1.2-rc2/Mac OS X Framework/CrashReporter.framework"
  s.osx.xcconfig = { 'LD_RUNPATH_SEARCH_PATHS' => '@loader_path/../Frameworks' }

Somewhat related to #57.

I'm positive this: CocoaPods/CocoaPods#1824 is also related.
