Bugfix: don't ship Steamworks.Linux, go back to shipping Posix for both OSX and Linux - this unblocks modders. - Linux got renamed to LinxuEditor and is only loaded for editor This takes us back to only shipping Posix.dll for both platforms, while enabling to wwork with the project in Linux editor. In theory, builds Linux -> Linux and Linux -> OSX should work as well, but not tested. Tests: Built Server Standalone for Windows and Linux from Windows. Confirmed in both cases LinuxEditor.dll doesn't get deployed, and in Linux case Posix.dll is.
