url doesnt support GET-params (fix inside)

[Deefjuh]

When initialising the uploader, the url does not support GET-parameters like so:

uploader = new ss.SimpleUpload({
      button: 'UploadButton', // HTML element used as upload button
      url: 'myfilepage.php?action=mydispatcher', // URL of server-side upload handler
      name: 'uploadfile' // Parameter name of the uploaded file
    });

The reason is that in the method _uploadXhr the queryURL always adds a '?' between the settings.url and ss.obj2string( params );.
Because the obj2string takes place on the fly, you also can't 'hack' the name param on init becuase it will treat the whole string as a the get-param i.e.:
name: 'myparam=test&uploadfile'

The fix is easy, albeit a bit crude:

    // Build query string
   queryURL = settings.url + ((settings.url.match(/\?.*/gi))?'&':'?')  + ss.obj2string( params );

Didn't bother to do a pull-request, as you guys might want to tweak the regexp.

Thanks for bringing this up. This is a good catch, I've never had to add GET params to the URL, so it's never crossed my mind before. Let me try this out and do some testing, but it's definitely something that will be added to the plugin.

Thanks again for pointing this out.
