A bug fix for the sequence.read() user function argument checking code.

Bug fix for the prompt.sequence module, the correct RelaxErrors are now imported.

Converted the sequence.read() user function to the new relax design.

This function now allows for sequences of molecules, residues, and spins to be read into the

The axed user functions are:
sequence.add()
sequence.copy()
sequnece.delete()
sequence.sort()

These no longer have any use.
