Title: In Vagrantfile, on Windows, use rsync for top level of shared folder

Use `rsync` for top level of shared folder so that symbolic links can be created in the `node_modules` folder.
Use a true shared folder for `opentreemap`, for convenience and so migrations made on the VM won't be clobbered.
