Fixed a bug on Firefox and the jquery that wasn't setting the tag data with innerText.
* Adds implementation of the loop checkbox and the fps text input field.
* Made all buttons and thumbnails to be wrapped inside a 'div' with id 'toolbar'
* Made the 'cheat-sheet' to be a little wider to allow loop checkbox and fps field to fit nicely
