Title: Added suport for excluding parameters in child errors.

Excluded properties on inherited errors did not work.

When rewriting the prototype chain in Constructor.define the
Child.prototype.friendly was overwritten and the original scope
was lost. This is fixed by restoring the original friendly method on the
prototype and recurse in the inherited prototype chain in the friendly
method.
