Ask GPG passphrase just in time
It would be nice to enter GPG passphrase only when necessary (by the time I really want to encrypt my communication), not during Gajim start up.
I rarely use GPG encryption so that it's annoying to enter my tricky GPG passphrase every time Gajim starts. On the other hand, I want to be able to instantly enable GPG encryption (and enter passphrase) when necessary.
