set min tie length for 1.3 scores

As per IRC discussion, I removed the setting of MinTieLength from read114.cpp (actually commented it out) so 1.3 scores will get same value as 2.0.  I wonder if we shouldn't do this for other settings where it makes sense to just pick up the 2.0 default.  I guess maybe sometimes we *want* 1.3 scores to be protected against changes in 2.0 defaults, so sometimes it is good to have the settings duplicated.  But here, I specifically want 1.3 scores to pick up the improvements made in 2.0.
