Added AOL

AOL had 2FA before everyone else, but they removed it a few years ago. :( http://securitywatch.pcmag.com/security-software/284240-aol-dropping-2-factor-authentication-support
Added AOL logo and changed name to AOL Mail

Changed the name because it is in the mail category and AOL does way
more than just mail.
