Small fix to work with Windows 10 and change of icon (thanks to @rayhaze for the idea).
To Install:
Recommend downloading the portable version and unzipping wherever you keep your portable apps (good option is C\Program Files\PORTABLE\Minimal Firewall, for example).
To Update:
If you already have the portable app installed, just unzip this release, and copy all of the contents into your current release (when the app is closed). Overwrite all the files. That way, it will keep the .json files which hold your settings.
