Suggestion: add `addy.io/login` redirection

[o0nd7ots]

Hello,

sometimes when using anonaddy I try to log in by writing addy.io/login into the browser search bar. However, there is no login page on the main website.

To enter it one needs to go to the subdomain app.addy.io, which prompts for a login.

I know that this is a neatpick so I can easily imagine ignoring this issue, but in the spirit of open source I bring this issue up.
