[sugar] What's left for Update.1

[Kim Quirk]

Jim,
I think this is way too much stuff for Update.1. We are in code freeze. We
have items 1 and 2 scheduled to go into RC2; I would suggest that we ONLY
pick up Spanish, where we really fell short in the current build; I don't
agree with holding up this build for either 4 or 5, as this feels like new,
untested code - perhaps there is no 'fix' even available at this time (I'd
need to see the arguments that this is blocking AND we have a fix); and I
agree that we need to look at 'Blocking' bugs that are still open to see if
we agree they are still blocking - or move them out.

People can argue otherwise (I'm open to a good discussion), but my
recommendation is to get this build out, with all the known issues well
documented.

Kim
