* Added wxsocket lib and sample (I hope I don't forget some file)
* Updated some wx data and makefiles * Updates on wxStream (reorganization) makefile for Windows will nearly follow wxSocket should work on wxGTK (I've tested it) * IPC over Network is included git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@684 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
