Spec/CMakeLists fixes for issue #21

 /etc/lighttpd/conf.d/obix-fcgi.conf is now a sym link

    ls -la /etc/lighttpd/conf.d/obix-fcgi.conf 
    /etc/lighttpd/conf.d/obix-fcgi.conf -> /etc/obix/res/obix-fcgi.conf

Note: rpm -ql obix-server still lists /etc/lighttpd/conf.d/obix-fcgi.conf

    rpm -ql obix-server
    /etc/lighttpd/conf.d/obix-fcgi.conf

(which is probably not a bad thing - don't want stealth files getting dropped onto a system)
