Add option to change name of a model when you omxSetParameters it

Usually, one uses omxSetParameters() to change something about a model - say fix or free parameters, so that the revised model can be fitted and compared. It would be useful to be able to change the name at that point. The attached patch modifies omxSetParameters() to add at the end of the arglist newname = NULL and if the newname is not NULL it changes the model name.
