Activated the quad_int flag for a number of the Frame_order.test_cam_quad_int_* system tests.

The quad_int argument for the flags() test suite method had been missed for a few of these tests.

Duplicated all Frame_order.test_cam_* system tests for testing the SciPy quadratic integration.

The Frame_order.test_cam_* system tests have all been renamed to Frame_order.test_cam_qr_int_*.
These have been duplicated and renamed to Frame_order.test_cam_quad_int_*. The flag() system test
method has been extended to include the quad_int flag which is then stored in the status object and
used in the base CaM frame order system test script to activate the frame_order.quad_int user
function.

Renaming of all the frame order target functions and PCS integration functions.

For consistency, all quasi-random Sobol' integration functions now use the 'qr_int' tag whereas the
SciPy quadratic integration functions use the 'quad_int' tag. This is not only in the target
function names but also the PCS integration functions in lib.frame_order.

Clean up for the frame order target function aliasing.

The Scipy quadratic integration and the quasi-random Sobol' integration target functions are now
aliased using the getattr() Python method to programmatically choose one or the other. The rigid
model has been removed from the list as it is not a numeric model, and the func_double_rotor()
target function has been renamed to func_double_rotor_qrint() to make it consistent with the naming
of the other target functions.

The RDC only optimisation now defaults to the *_qrint() frame order target functions.

This restores the earlier behaviour prior to the restoration of the SciPy quadratic integration.

Fix for r25994 - the cdp.quad_int flag was not passed into the target function properly.

Fixes for the missing cdp.quad_int flag.

If the cdp.quad_int flag is missing, this is now set to False before setting up the target function
class. The previous behaviour was that the frame_order.quad_int user function must be called prior
to optimisation. Now it is optional for turning this flag on and off.

The cdp.quad_int flag is now passed into the target function for the frame order calculate() method.

This is for the minimise.calculate user function backend.

The quad_int argument for the frame order target function class now defaults to False.

This is so that quasi-random Sobol' numerical integration will be used by default.

Removed the call to the frame_order.quad_int user function in the auto-analysis.

This was the result of a bad restoring merger of an old commit.
