Update Crashlytics.
Fix build for App Store submission.

I guess I wasn't supposed to copy the framework into my app extension. Answers my earlier question of "will we be duplicating the bundled smilie store" (no).

Moving the Headers phase up for Smilies.framework allows us to use the #import <Smilies/SmilieManagedObject.h> within other public headers.

And Xcode "fixed provisioning profiles" for me, which added some pointless-looking empty-string PROVISIONING_PROFILE settings. Whatever.
