Prompt to accept and pin self-signed certificates

[AutoImport-nodiscc]

Hi, thanks for this promising app. The steps necessary to accept a self-signed certificate arre cumbersome and imparactical though. I have no way to save my server’s self signed certificate from my phone and have to rely on a desktop Firefox to save the certificate as DER, copy it to my phone’s SD card - and even this has failed so far.

Maybe you could prompt the user if a self signed certificate is detected, ask if he wants to accept it (display the fingerprint), and pin the certificate (display a scary message if the certificate changes in the future). https://github.com/owncloud/android does exactly this.

What do you think?

Thanks! Closing because related to issue #3.
