[Golist] TweenBencher 1.5 + Go 0.3.1

[Moses Gunesch]

SVN commit, includes TweenBencher.

(If you've updated in the last 12 hours, please update again, I had to  
refactor the TweenBencher directory structure and fix the HTML welcome  
page)

BUG FIXES
----------------
Donovan found a nasty issue with managers getting stored multiple  
times – major oversight on my part, thanks man!

NEXT STEPS
-------------------
It seems that other recent updates to GoEngine have slowed Go down as  
well. I'm going to try and optimize it.

Thanks friends,
