[liberationtech] Mailvelope: OpenPGP Encryption for Webmail

Because Thomas (the original developer of Mailvelope) wanted to let
the extension work as it was, with the unsecure encryption inside DOM,
I decided to fork his project and make a new one, which both encrypts
and decrypts in a secure chrome pop-up.

It's here, it's called ChromeGP.
https://cryptoparty.cz/ChromeGP/

Available on chrome web store here
https://chrome.google.com/webstore/detail/chromegp/pebhdbojdpjfidjbneklefmpojncdpmf

and on github here
https://github.com/runn1ng/ChromeGP

There are two big issues with it - first is missing signing/signature
control (which should be easy to implement, but we will see) and the
second is OpenPGP's trouble with zip compression inside PGP (which,
unfortunately, causes the default Thunderbird/Enigmail encryption fail
to decrypt, I think).

Feel free to share and/or criticize :)
