relax SVN archive

Created the _det_install_path() status singleton method for better determining the install path.

This will be used for the Mac OS X applications whereby the current logic of using sys.path[0]
fails miserably!

Reverted r15781, as this is no longer required.

The command used was:
$ svn merge -r15781:r15780 .

Changed paths:
M /1.3/setup.py

Shifted the build and dist directories out of the relax base directory.

This is for the Mac OS X application building, and is to prevent the 'dist' directory from being
recursively copied into itself. This seems to be a recently introduced bug.
.....

Prepared the multi-processor package for the import mechanisms of Python 3.

This new mechanism is present in Python 2.7 now, and the code falls back to the old method when not
present.

Fix for the py2app setup.py script for Mac OS X application creation.

The list of data files to include with the app is now properly formatted.

Complete redesign of the py2app setup.py script for building Mac OS X applications.

The script has been converted into a class called Setup which performs all the actions. All files,
source or otherwise, are now stated as data files to be included in relax.app/Contents/Resources.
All relax modules are specified by the py2app 'includes' option so that they are all included within
the relax.app/Contents/Resources/lib/python2.X/site-packages.zip as *.pyc files. These changes are
needed for the newer versions of the py2app and setuptools Python packages.

The py2app part of the setup.py script now throws a RelaxError if the setuptools module is missing.

Added the relax prompt icon to the main GUI window toolbar.

Added the larger sized application-x-executable-script Oxygen icons.

The relax GUI is now robust and able to withstand a call to the reset user function.

This could have occurred if the user ran a script with a reset() call, or if reset() was typed at
the GUI version of the relax prompt.
