setup a static framework from iphoneos and iphonesimulator static libs

Framework.sh

#!/bin/sh
#
# Framework.sh -- static iOS framwork packager
#
# This script combines two static libs (iphoneos and iphonesimulator) into one,
# and then packages it into a static, app-store friendly, framework.
# A chosen configuration is also packaged into a tarball for easy releases :)
#
# Original Script by Pete Goodliffe
