Added support for VPN Tracker 8

This adds support for VPN Tracker 8. According to there docs the config files are stored in 4 different places:

If you want to make a file-system level backup, you can find your VPN connections and related settings in the folder
/Library/Application Support/VPN Tracker 8
Your Secure Desktop(s) are stored in the folder
~/Library/Application Support/VPN Tracker 8
Your preferences are located in the files
/Library/Preferences/com.equinux.VPNTracker8.plist
~/Library/Preferences/com.equinux.VPNTracker8.plist
Please make sure you include these two folders and the two preferences files in all your backups.

Just following there support documents of where stuff is, I have changed it to remove ~
