ICeCoffEE 1.4 and preliminary 1.4.1 changes. Sorry, I forgot to
commit version 1.4 when it was released, so the precise source for
that release has been lost.
See the release notes for details of what changed in these versions.
1.4 was a significant feature release; 1.4.1 is a bug fix for 10.3.9,
incorporating up-to-date Unsanity Installer and APE.
package-ICeCoffEE.sh: use xcodebuild instead of pbxbuild.
