* Adding sckint.cpp to various makefiles. * Fixes in threadpsx.cpp (Pause/Resume) * Fixes in threaded event dispatching * Added Clone() to wxObject * Implemented Clone() in wxEvent and wxSocketEvent * wxSocket sample save the data got from the URL in test.url (this will change) * As I only tested wxSocket on Linux Redhat 5.2 I disabled it by default on Windows, Mac and Unix platforms. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@2289 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
