Add a test for correct integer komi
Fixes .gitignore problem that was preventing us from committing .sgf
files. Adds those files.
Change scoring to allow for ties.

Scores are now doubles and scores of zero are ties.
Some tests had to be changed because they had expected
scores hard-coded using the old method of calculation.
Move toward fractional wins.

SearchNode.recordPlayout now takes a fraction of a win to record.
There is now a test to see if fractional win updating is correct.
Modify players to handle fractional wins.

MctsPlayer no longer ignores ties. Instead
it updates the tree with half wins for both colors.
Additionally, wins are now stored as win ratio and
number of runs, from which total wins are calculated
as needed. All test pass and Orego appears
to play gnugo reasonably.
Looks for Orego in the right place on Fido. Also looks for files with
.sgf extension when collating experiment results.
Fix SGF output format

A single node may have at most one comment
but Orego was putting multiple comments into
the last node. Fix this by splitting up comments
into separate nodes.
