[Feature Request] Custom WndProc

[hamarb123]

Hello, I'd like to have custom WndProc handling on the WinForms version of my application. I've looked through your code and noticed that there is no way to do this currently (without reimplementing a large amount of code that you guys maintain). What I suggest is having a field in EtoFormBase with the type of the delegate implemented as such delegate void WndProcDelegate(ref swf.Message m);. This delegate is then called at the end of your WndProc method (if not null) and it is the responsibility of the one who set the field to ensure that it doesn't crash or anything, but of course any method of having custom WndProc handling would be fine.

I've implemented this myself, with the permission of an owner, I'll open a PR.
