Introduced hamachi-override.ini file.
hamachi.ini is used and managed by Hamachi. This in particular means that
any changes made to this file while Hamachi is running are ignored and
To add custom settings such as RoutedTunneling, BindTo or TxRate or to
override default ones hamachi-override.ini file should be used.
When Hamachi starts, it first reads hamachi.ini and immediately after
this it loads hamachi-override.ini. Any settings found in latter override
any values loaded from former. Hence the name.
Lastly, Hamachi never modifies hamachi-override.ini file.
