That looks much better - and led me to fix the code which skips over
considering rollouts already done which simply wasted time.

A couple of minor things:

The html, txt and Gol exports of rollouts filters are missing a space
between the outputs:

keep the first 0 0-ply moveskeep the first 0 1-ply movesCube: 2-ply ...

They don't show some other details, like the accept and accept
thresholds. On the other hand, most of the time this will be far move
information than people want. It's also usual that rollouts are done
for multiple moves with the same rollout settings, in which case
repeating it for each individual move clutters the output to no real
purpose.

What would people's thoughts be on:

Providing a couple of option setting for all rollout exports:

1) detailed on/off
   When off, output is the same level as prior to your changes - 

   1296 games, Mersenne Twister dice gen. with seed 19856543 and
   quasi-random dice   
   Play:   2-ply cubeful 100% speed [world class]

   Detailed would give the move filters and all the other possibly
   relevant settings - by player if the differ, cube and chequer if
   they differ, rolloff database if used, move filters etc.

2) summarise settings:

   When exporting a set of rollout results, examine the rollout
   contexts and, if they are identical, per move simply output for
   each move:

   1296 games, settings given below

Then at the end of the output give a detailed/not rollout setting. If
any rollouts have different settings, then do detailed/not summaries
per rollout.

Note that we are now saving and restoring the complete rollout context
in .sgf files, so if someone does a rollout and saves the result, then
if they ever want the detailed description of the rollout, it can be
recovered from the .sgf file.
