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.

The DMG image file is now being sent to the parent directory '..' rather than the base directory.

This fixes the problem of the DMG file packaging itself into relax.app/Contents/Resources, creating
a 120 Mb file rather than a 60 Mb file!!!

Bug fix for Mac OS X - attempt at killing the Carbon.Evt.TickCount problem by removing argv emulation.

threads.

The suggestion from
http://stackoverflow.com/questions/3461983/evt-tickcount-not-found-with-python2-6-on-osx-10-6-3 was
used, where the py2app 'argv_emulation' option is set to false. For this to work in relax, the
command line argument parsing had to be turned off and default values set in the Relax() instance
namespace.

The scons binary_dist target on Mac OS X can now overwrite a pre-existing DMG file.

This is just an argument to the Mac hdiutil program.
