Windows RegisterClass: Use new RegisteredClassFactory (window class), Misc.

This solves the issue when an applet is started/stop and started again,
or another applet runs in the same JVM.
Also soves the issue for multiple JVMs.

RegisteredClassFactory can be instanced to manage one shared window class,
currently in use for GDI's dummy window and NEWT.
A class base name and a window proc handle must be passed in the factory cstr.

Before registering, the class is tested if already exists,
eg another applet in the same JVM.
If registration fails, the class name will iterate until successful or MAX_INT reached,
eg if multiple JVMs are running.

Added NativeWindow Common Native Code.
