windows: improve start vagrant on boot

[dogi]

• [ ] make script "Username" independent
• [ ] script copies itself into the "users" startup directory

@dogi I just wanted to clarify what you mean by the first item on the checklist 'make script "Username" independent' . I wasn't sure what you meant by that.

Also, do you want the script to copy itself into "all" users startup directory or only the local user's startup directory?

@pranesh-s Good questions! What @dogi meant by "making the script username independent" is that currently these two scripts which are meant to start vagrant on boot refer to a user called ole, which means it won't work unless the user is named ole. This needs to be changed so the scripts work for people with different usernames on their computers.

Also, I think it's fine for the script to only copy itself in the local user's startup directory.
