ui.autocomplete does not encode params prior to getJSON call

The Autocomplete plugin does not encode user input "out of the box" when using a remote data source - it just pipes it straight into a getJSON call.

As you can imagine, depending on the data sent, you may or may not get away with this.

This can be sorted out by including:

var prop;
for(prop in request) {
   request[prop] = encodeURIComponent(request[prop]);
}

...prior to the getJSON() call on line 248.

Please find attached a copy of the unminified autocomplete source with this added.

Note the new lines of code on 237, 249-251.
