Look! Mist now has images that contain objects, including an ElfInfo object that provides the ELF header to the file, Method objects that can be executed, and FreeObjects that are not allocated for any other purpose. ElfFile has become MistElfWriter, with changes to support writing of an image with an ElfHeader object rather than just a program with no objects in it. Rework of the previous Disassembler Tests and Fog Tests for the new world of objects and images. The PrintH test has been dropped since it depended on the absolute address of the code to work, and the later, longer, tests cover all of that functionality.
Update baseline to reflect package restructuring for images and objects.
Baseline was missing the fact that the disassembler is required in order to run disassembler tests.
