Moved the lipo code for creating a universal static library out into a separate target, so it does not run every time the library is build.
Fixed a bug where addSublayer: was called and passed a nil object if the hostedGraph property had not been set.
Removed TestMerge and system tests. They are not up-to-date. If someone wants to add this back in future, they can just retrieve the old source.
