Bug fix for the spectrum.replicated user function for when it is called twice with the same IDs.

Bug fix for the relax GUI spin viewer window.

When right clicking on nothing in the tree view, an error would occur. Now, instead, a special menu
pops up with a single entry for loading spins.

Fix for the building of the relax C modules as universal binaries on Mac OS X.

The linking was not functioning correctly, and the resultant module was build only for i386.

Updates and clean up of the Mac OS X framework building document.

Updates to the instructions for building a Mac OS X Python+modules framework.

Added a document describing how to build a 3-way (i386, pcc, x86_64) Mac OS X Python framework.

This is needed to create the DMG distribution file.

Added a script which is used to validate the binary architecture of Mac OS X Frameworks.

The relax Mac OS X dock icon is now turned off when using the wxGTK build of wxPython.

This prevents a little grey frameless window appearing with the largest of the relax Ulysses
butterfly icons in the centre.

Improved the relax info print out for the installed python packages.

This now shows more information for the wxPython version, and formats the output based on maximum
widths to handle different situations.

Removed the ppc64 build target for the relax C modules on Mac OS X.

This architecture is not supported by the recent Xcode frameworks, so it has been dropped. ppc64
users can manually compile the modules, if desired.
