Use SOCKS5 for Tor rather than HTTP proxy

[lu-ckystars]

its been this way for a long time. i use the alpha version but the regular does the same. I'm pretty sure the rest of the traffic does get sent over for, but perhaps in a weird way:

would it not be better to have it using orbots socks5?

There's some example code here for using a SOCKS proxy with an Android WebView: https://github.com/guardianproject/NetCipher/blob/master/sample-webviewclient/src/sample/netcipher/webviewclient/GenericWebViewClient.java#L56

We'll also need to update the OkHTTP code, possibly to use a custom socket factory.

This was the original reason why a SOCKS proxy wasn't used: https://github.com/square/okhttp/issues/2315
