Created the RelaxAlignError error class for use by the rdc.copy and pcs.copy user functions.

Fix for the RDC and PCS data copying system test script - the sequence is now also copied.

Created the RelaxNoAlignError error class for use by rdc.copy and pcs.copy.

Reactivated the rdc.copy and pcs.copy user function front-ends.

The backends are missing, so relax is currently broken.

Created the N_state_model.test_data_copying system test for the rdc.copy and pcs.copy user functions.

These user functions do not exist yet, but this test will be used to implement them.

Reverted r17952 as well as this is fatal for most frame order models.

The command used was:
svn merge -r17952:r17951 .

Reverted r17957 and r17958 as these are no longer compatible with the previous reversion.

The command used was:
svn merge -r17958:r17956 .

Reverted r17954 as this is fatal for all the other frame order models.

The command used was:
svn merge -r17954:r17953 .
