Implement file scheme

[IJMacD]

Although the primary focus of dploy is obviously FTP/SFTP I found it useful and trivial to implement the file scheme.

I realise this isn't the direction dploy is going in but thought it others might find this useful.

Example config:

prod:
    scheme: file
    basePath: Y:\noticeboard
    user:
    pass: "none"
    check: true
    path:
        local: dist/
        remote: /
