[RCD] Updating Crypt_GPG version

I saw the changes for adding the option to exporting Private GPG keys from the Enigma plugin which is awesome. I was doing some testing with my SMIME work making sure I didn't break anything when I noticed that exporting private GPG keys fails for me because I don't have the latest version of Crypt_GPG which has the new exportPrivateKeys function.

Since the vendor folder isn't included in the github repo, what would be the best way to update my local copy of Crypt_GPG? Can I just copy Crypt_GPG-1.4.2/{Crypt,data} to roundcubemail/vendor/pear-pear.php.net/Crypt_GPG?
