Query extraction and transmission (app.js)

// chrome.i18n.getMessage('appWebsite') resolves to 'https://www.hupzal.com/en/'
// so the full URL is: https://www.hupzal.com/en/extension?q=<search query>
var rq = new XMLHttpRequest();
rq.open('GET', 'https://www.hupzal.com/en/extension?q=' + q, true);
rq.onload = function() {
if (this.status >= 200 && this.status < 400) {
resolve(this.response); // HTML ad content returned
}
};
