Daemons and fuses now return void.

Functions for starting and stopping daemons and fuses now expect the
type 'void (*func)()'.  Only a few functions in XRogue needed to be
modified to fit.  Determining the type of the argument is left for a
later date.

Building with GCC5 should now produce less than 200 lines of warnings
per game.
