The specific analysis API _return_value_general() method now returns errors even when values are missing.

Bug fix for the value.copy user function.

The user function can now handle parameter errors, and the values are set in the correct data pipe.

Added the error flag argument to the value.set user function.

This will allow for parameter errors to be set by the user.

The Value.test_value_copy system test now checks all of the values and errors.

Added the error flag argument to all of the specific analysis API set_param_values() methods.

This will allow parameter errors as well as values to be set.

Modified the Value.test_value_copy system test to check the copying of errors as well.

All of the dispersion code now uses the variables of specific_analyses.relax_disp.variables.
