bug 10674 continuation. Allow SBSv1-style build config names to co-exist with newer SBSv2 configuraiton names that use aliases. This does not use project converstion, just adds the support to differentiate between the two. Also, write new .cproject data to a SBSV2_DATA_ID node (which is not currently read, but to be used for future purposes)
