Cleanup types and method arguments

[KasimAhmic]

I'm currently using Windows C types to make writing the bindings easier as I can easily identify what I need to do where, for example, if I see LPWSTR or LPPOINT I know I need to deal with buffers or structs. Before the initial release, these should be cleaned up and converted to JavaScript types.

1. Remove Windows C type TypeScript aliases
2. Update all method argument and return types to be JavaScript types
3. Update all method argument names to be easier to understand
   • hWnd to windowHandle
   • szTitle to windowTitle
   • etc...

Closing this as the C++ rewrite (#4) negates the need for this.
