Add version to folder name of build output

[jlokanis]

When building something from a build spec in the project, I want the option of having the build version included in the folder name where the output is placed.  That way new builds do not overwrite the previous builds and I have some way of knowing what version a build is without having to first install it and see what I get.

I will clean up the old builds manually myself, so that is not an issue for me.
