[Golist] Go 0.4.2

[Moses Gunesch]

Log:
version 0.4.2, a significant update:
Totally new tests package with GoTestBase class and tutorial classes,
The tutorial class SizeTweenMG renamed slightly (was Mg) and updated a  
little,
GoItem now sports a smoother defaultPulseInterval of 33,
Sequence Looping feature added: repeatCount & currentCount props added,
Sequences now should not be GC'd while running if you don't store a  
ref to them,
SequenceCA: Many changes and fixes mostly dealing with _trailingTweens,
TweenBencher updated for use with this version.


I wanted to give special thanks to Karsten Goetz for helping me  
convert the tutorial files into classes, and also to Aram for  
suggesting the looping sequence feature & pointing out the GC issue  
with sequences. Also to Donovan for stoking up this last round of  
activity.
Thanks guys!
  :)
