After the java build team moves JDK7 entirely to vs2010, there are some additional things we need to do in the install decouple area:

-Address the hard-coded PluginVersion.h for the fiu and installerdll projects. This will be an issue when we get to 7u1.

-have the installer makefiles trigger the building of fiu and installerdll projects, rather than having the binaries pre-built and in the repo like they currently are

-I think there may still be some dependencies on deploy/src/common/native, or something like that

-removal of fiu/regutils/regutilsmsi/auto-update files from the deploy tree. I may or may not get to that as part of phase 1
