* FuncProcessor.cs: Corrected the XPath for signature overrides.
* Structures/Parameter.cs: Avoid qualifying IntPtr fully ((a) it's unnecessary, since we have "using System;" already and (b) the namespace qualification is not portable to C++).
* Settings.cs: * FuncProcessor.cs: * Structures/Type.cs: * Structures/Constant.cs: * Structures/Delegate.cs: Do not hardcode namespace separator to ".".
