simulator build produces _CodeSignature directories

[kambala-decapitator]

as a workaround I use:

:post_compile => Proc.new { |installer|
  system('find Rome -type d -iname _CodeSignature -exec rm -rf {} +')
}

turns out it's xcodebuild's fault, a better solution is to use CODE_SIGNING_ALLOWED=NO build setting
