Updated the N-state model analysis code to handle the per-alignment tensor fixed flag.

This allows subsets of tensors to be optimised while the others are fixed.

Updated the relax data store alignment tensor objects to allow for the per-tensor fixed flag.

Syntax error in the align_tensor.fix user function front end.

Syntax fix in the all_tensors_fixed() function.

Renamed all_fixed() to all_tensors_fixed().

Created the generic_fns.align_tensor.all_fixed() fn for determining if all tensors are fixed.

The alignment_tensor.fix user function is now tensor specific.

This will allow a subset of tensors to be optimised while the others are kept fixed. The specific
analysis code will need to be updated for this.

Bug fix for the grace.write user function for when the spin ID is specified.

The spin ID was previously unused!

Some small fixes for the new test_cam_kkalpha_plot1() system test.

Created the test_cam_kkalpha_plot1() system test for checking the grace plotting of mixed data.
