 Webmud3: third generation of the UNItopia Webmud as open source project.
 
 In this early stages (Versions < 0.1.0) it's not for production.
 Version 0.0.2 delivers a configurable list of muds in frontend/config/config.development, so that the development mode can be used as local browser-mudclient to multiple muds.
 Version 0.0.3 added ANSI colour support
 Version 0.0.4 fixed an ANSI colour issue and renamed frontend dir to backend.
 Version 0.0.5 implmented telnet_neg: echo,terminaltype and naws. started with GMCP support.
+Version 0.0.6 implemented sound on top of GMCP, working with UNItopia so far.
