Only show the last few characters of license key in About
Makes it more difficult for other people to copy our valuable license key just by viewing our "About BatteryBar Pro" menu.
In older versions of BatteryBar, the license key wasn't displayed at all. Users requested to have the license key as a reference so they could look it up if they lost the email. So one way or another, someone's going to be disappointed.
I'm open to any ideas you might have to make both groups happy.
