new tcl-controlled prescale variables

Hello,

I have created two new tcl-controlled variables. They are:

prescale (T/F, default F)
prescale_factor (integer, equal to 1 or greater, default 1)

These allow you to look at a fraction of the data, distributed
uniformly throughout a run. This will be useful for offline
analysis during the run.

I did not change the calculation of the run statistics, because
I thought there might be more to it than just scaling the times
by the prescale factor. (input needed from Arne) Instead, I
print out the prescale factor in the same box as the statistics
so that at least people will know what it is. We can improve this
when it's clear what to do.
