Fix for MNU when viewing admin upload statistics on Squeak 6

[Scott Gibson]

I am using Squeak 6 and Aida 6.8 final 2. When viewing the Uptime page as admin Aida will give a MNU.

I'm a noob but here is the code change that I made to fix this issue in Squeak 6. The change is in ScaledDecimal>>printDotString and the changes are:

n := (fraction numerator) * denom + ((fraction denominator) bitShift: -1) // (fraction denominator).
(fraction numerator) < 0 ifTrue:
[stream nextPut: $-.  n := n negated].

Thanks!

Scott
