Add support for armv7s (iPhone 5)

[AdamSwinden]

Hi,

Build fails with an error when building an app with BlocksKit using iOS 6 GM SDK for device using the default Architectures build setting "Standard (armv7, armv7s)".

This is because an armv7s "slice" is missing from the latest framework.

Sorry gents! I have every intent to add armv7s support, today even. Things are just complicated be because we've still had armv6 support. Hang tight!

+1 and thanks for your hard work!

This should be fixed in the 1.5.2 rerelease. Thanks for bringing this to our attention.
