Added a cheat parameter to enable the reuse of the final data set for a

number of iterations before starting the real backwards evolution of the
level set function. If everything is stationary this should be okay. If it
is only approximately stationary, the evolution of the level set function
is dubious but the trial surfaces might get closer to the real event horizon.
Testing is definitely necessary. Don't use it unless you really know what you
are doing.

The implementation is also slightly dubious, since I modify cctk_iteration
to start out with negative iteration numbers. There might be a more elegant
way of doing this.
