Fix HTTP/S juggling.

[indolering]

Querying DNS must ALWAYS occur over SSL. However, Firefox will block some HTTP content from loading in a page with HTTPS enabled.

Thus, in order to isolates DNS from possible malicious MTM attacks

1. https://speech.is -> webWorker : {lookup:urn}
2. https://speech.is <- webWorker : {name:urn, value:{http:FQDN}}
3. https://speech.is: load(record.value.http)
   ...

function load(FQDN){
    if (isHttps(FQDN)){
        iframeLoad(FQDN);
    } else {
        forward self to "http://speech.is#!destination=" + FQDN;
    }
}

4. http://speech.is#!destination=example.com:

if(location.hash.beginsWith('!destination='){
   //load http://example.com
} else {
  //load  https://speech.is + window.location.hash
}
