Add Type and Icon parameters to MessageBox

[Corrado]

I think that would be useful to add Type and Icon parameters to MessageBox procedure.
Similar to panel's ShowMessage parameters for the message bar.
Thank you

Why not? It could be useful in some cases.

I've created the ticket NPQ02342 that allows me to keep track of this thread.
When it'll be analyzed you'll see it in the Instant Developer Roadmap.
