Much better low memory handling. When a run stops because of lack of memory, the soup can still be saved. Window positions are saved between runs. Soup file version checking now using a file version number saved in the soup file, and not MacTierra's own version number. The menagerie list now uses an LDEF stub, so that it runs native on both platforms.
All files are cross-platform compatible still.
Now a fat binary. Soup and menagerie files are compatible across platforms. Implemented the hierarchical genebank window, which necessitated further changes to the soup file format. The plotting of bar graphs with lots of columns is a little more sensible. Also disable unavailable items on graph popup menu.
