[BlackBerry] WebView/Browser cause blank screen when selecting a dropdown field.
https://bugs.webkit.org/show_bug.cgi?id=90241

This issue is caused by single quotes in option's labels.
We should use the escape character of single quotes in JavaScript's string which
starts and ends with single quotes.
So we replace lablels' single quotes with its escape character during generating the
select popUp's HTML.
