Create box-thin binaries that don't bundle any libs

If you are wanting to bundle CommandBox on a Docker image, etc and the CommandBox home is already unpacked and in place, the binary is unnecessarily large--especially now with pack200 turned off. Add to the build a box-thin.exe that can be swapped out with the "full" CommandBox binary after the home directory has been unpacked the first time. It will still work the same when executed, but is a fraction of the size.
