I didn't try it, but would have imagined that calling setFilter("")
would do the trick.  If not then if you decide to add this feature I
would suggest that you modify loadExpressionString() so that if the
expression is an empty string then it's the same effect as setting the
expression to NULL.  This way all flavors of MapScript will benefit from
this change at the same time without having to define 'None' or NULL in
every language.
