+ Added an *almost* unix-like fork system for windows. Insp will create a secondary process now if nofork isn't specified and pipe its console output back to the originator's. If there is an error during startup, it will show too.
* Fixed m_spanningtree project (cmd_rsquit was missing) git-svn-id: http://svn.inspircd.org/repository/trunk/inspircd@7255 e03df62e-2008-0410-955e-edbf42e46eb7
