Update version.

Change version shown in this to 3.4.

Changes to work with my release script:

Changed install path to /
Made libMachObjC.a an explicit dependancy, so that building with xcodebuild works.

Updated description of --sdk-root in usage text.

Updated a few copyrights I missed.

Added some bundles to the list.

Removed formatType and deprotect from "all" target.

And show the Objective-C Garbage Collection status.

Export the source using a shell script phase, only run during install.

Changed version to 3.1.1
