There have historically been a lot of different versions in disparate 
locations (LL SVN, uBrowser Web site, internal sandboxes for example) 
and since this latest version is quite different from the one we've been 
using in the SL client, I wanted to call it out as different.

This is the version we use in the current release candidate for 1.19.1 
and will be the version we use going forward.
