[sldev] SNOW-25: XUI updates for Snowglobe

[Rob Lanphier]

Hi all,

I did some XUI updates for Snowglobe, trying to zero in on just the
strings that are viewer related (as opposed to referring to the Second
Life service, website, or community, for example).  Here's what I came
up with:
https://jira.secondlife.com/browse/SNOW-25

I'll check in the default/en-us version later tonight or tomorrow, then
move onto the other directories after that if all goes well.  Let me
know if you see any mistakes there.

Rob
