QScriptValueIterator: fix missing non-enumerable values

Added an extra argument to JSObject::getPropertyNames() that
specifies if the non-enumerable properties (those with the
DontEnum attribute set) should be included or not.

Tried looking at using a unsigned as an attribute-inclusion
or exclusion filter, but the semantics of either the calling
or the callee code would be very strange so I opted out.
