This is to show a problem in the align_tensor.copy user function when copying all tensors between
data pipes.

The align_tensor.copy user function 'tensor_from' argument can now be None.

This is to enable the copying of all alignment tensors from one data pipe to another.

Modified the pipe_control.align_tensor.align_data_exists() function to handle no tensor IDs.

If no tensor ID is supplied, this will then return True if any alignment data exists.

Improvement for the align_tensor.copy user function.

The user function has been modified to allow all alignment tensors to be copied between two data
pipes. This allows the Align_tensor.test_copy_pipes system test to pass.
