Speaker notes won't show slides if presentation url contains question mark

[lizatop]

When I have a reveal.js presentation opened with a ? in the URL, I can not get the slides in the speaker notes loaded, because the iframes url's params are appended with a ? and browsers do not like two question marks in an URL.

Suggested fix in /plugin/notes/notes.html.

change :

var currentURL = data.url + '?' + params + '&postMessageEvents=true' + hash;
var upcomingURL = data.url + '?' + params + '&controls=false' + hash;

to :

var urlSep = (data.url.indexOf('?') > 0) ? '&' : '?';
var currentURL = data.url + urlSep + params + '&postMessageEvents=true' + hash;
var upcomingURL = data.url + urlSep + params + '&controls=false' + hash;

Using 3.2.0, I can open the slides in the speaker notes when path has ? in Safari, but the parameters are not passed/applied properly.
