Fix for the MS Windows BAT file so that relax can be launched from the Windows PowerShell.

Fix for the dauvergne_protocol model-free auto-analysis with the deletion of data pipes.

Now only the data pipes created by dauvergne_protocol are deleted. This fixes the problem whereby
data pipes from other analyses are deleted by dauvergne_protocol, breaking the GUI.

Bug fix for the Rx auto-analysis GUI test.

The read only spectrum ID combobox values should be set with SetStringSelection().

Improved the RelaxError messages in validate_sequence().

The invalid data is now printed so that the user can see why it is invalid.

Fix for the spin viewer window for MS Windows.

The get_info() method now catches if no item is selected in the tree before trying to get the Python
data from it. Asking for Python data from a missing TreeCtrl item ID works on GNU/Linux and Mac OS
X, but not on MS Windows.

Bug fix for MS Windows - the main relax window is now maximized on start up.

Improved the print outs of the scons 'binary_dist' target for Mac OS X.

Modified the 'clean' scons target to remove the py2app build and dist directories.

Created the 'scons binary_dist' target for Mac OS X.

Typing 'scons binary_dist' on a Mac will now create a DMG image of a universal Mac OS X application.

Added the Mac OS X DMG distribution file names to the scons script.
