New example IRC Client for DlangUI

[Vadim Lopatin via Digitalmars-d-announce]

Hello,

I've added new example for DlangUI - IRC Client.
It's located in dlangui/examples/ircclient and available as 
dlangui:ircclient package.

For this application, AsyncSocket implementation is added to 
DlangUI.

Best regards,
     Vadim
