Deleted the ancient, unused 'quit' argument of the relax interpreter object.

This code was identified in a post by Troels Linnet at
http://thread.gmane.org/gmane.science.nmr.relax.devel/5000/focus=5003.

This argument never worked correctly and has not been used for many, many years. Many code paths in
relax needed to be updated to remove the argument.

Simplified the CaM frame order system test base script.

The class variables are now always defined, so checking for their existence is pointless. The
CONE_S1 is now also defined in the base script as a class variable.

The second pivot is now being passed into the frame order target function class.

Changes to the frame_order.pivot user function.

The 'order' argument has been added to allow for multiple pivots to be present. The user function
backend will store these as cdp.pivot, cdp.pivot2, cdp.pivot3, etc. The 'fix' argument is now
defaulting to False to make sure it is always boolean.

Updated the CaM frame order double rotor system test script to have the correct two pivots.

Changed the handling of the pivot point in the CaM frame order system tests.

The pivot point is now a class variable, rather than being hardcoded into a function. The handling
of a second pivot has also been added.

Updated the test_suite.system_tests.scripts.frame_order.cam package __all__ list.

Class variable cleanup for the CaM frame order system test scripts.

The variables are now all defined in the base script and only overwritten when needed by the
individual tests.

Capitalised the class variables of all of the CaM frame order system test scripts.

Added a simple script for analysing the Eigensystem of the CaM frame order double rotor test model.
