Create a completely new lua state upon USR2 reconfigure

This way, global variables set by the scripts don't persist between hard reconfigures.
I also cleaned up the reconfig-handling code in fluxbox.cc. Instead of three reconfig functions
(real_reconfig, timed_reconfig, reconfig) we have just one.
