Control Panel Modifications/Fixes (Theme Prettification) 

Not sure if you want to pull this but you can see a demo of the changes: [here](http://bendol.github.io/Pokemon-Lightning-Yellow/iodinegba/index.html)

* The control panel will auto hide when you click on the canvas (while playing).
* Then control panel will auto hide when you click play.
* You can toggle the control panel using the side toggle button.
* Can define the default control options in the html now.
* Maintains scale when the control panel is opened while playing.
* Can also select the control check boxes by clicking on the text now.
* Overflow scrolling is now working correctly on the control panel.
* Added the Bootstrap3 theme.
* Added a IodineGBA logo/watermark.
* Added an option to download the standard GBA bios.

I am making use of the JQuery animations for show/hiding. If you don't want to retain JQuery as a dependency feel free to convert it to use plain DOM manipulations. JQuery library is 90kb which is a tiny dependency anyway.

Made things easier for me using this emulator so figured I'd make a PR! :)
