* Added wxMMedia in the repository so people interrested in it can work on it
* WARNING! It is quite unstable on Windows and it doesn't work on Linux for the moment because I didn't finish fixing the CODEC stream. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@975 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
