Switch the normalisation option in WritableWaveFileModel from normalising on read to normalising on write, so that the saved file is already normalised and therefore can be read again without having to remember to normalise it

/**
 * Metadata associated with a transform.
 *
 * The transform ID is the same as that used in the Transform class.
 * It is intended to be computer-referenceable and unique within the
 * application.
 * 
 * The name is intended to be human readable.  In principle it doesn't
 * have to be unique, but the factory that creates these objects
 * should add suffixes to ensure that it is, all the same (just to
 * avoid user confusion).
 *
 * The friendly name is a shorter version of the name.
 *
 * The type is also intended to be user-readable, for use in menus.
 *
 * To obtain these objects, use
 * TransformFactory::getAllTransformDescriptions and
 * TransformFactory::getTransformDescription.
