[RsR] estimators based on random samples... - should be random

I clearly advocate the use of R's random numbers throughout.

I think that an argument seed= is not needed, since the handling
of random numbers is easy without it. The user can call set.seed
before calling lmrob and, if needed, store the old seed and
reset .Random.seed to this value later.

As to the naming issue, I dislike the underline as a part of a
name, because I use ESS. I prefer names like
lmrobMM
lmrobS

Is there a need for method="fastS"? Will there be other
submethods of S-estimators? If so, I again like the main things
first:  Sfast  instead of  fastS .
