Added mobile support to jsnes

[joeheyming]

Using hammer.js I added a tap/hold/release function that has been tested on an ipad.
I provided mock up html and js files that work on a dummy apache server.

I'm used nipple.js in my private fork and it working awesome on iPad. It can solve problem with virtual joypad.

Thanks @joeheyming! It'd be great to get this supported properly, rather than it just be an experiment.

I think at the very least, we should have some built in code that does browser detection, and if it is a mobile browser, attempts to add overlay controls. That can be in the main emulator -- I don't think it needs to be separate.

@drakmail is the code in your fork good enough for a pull request?

@bfirsh unfortunately the fork is full of dirty hacks 😅 Also I'm not sure that I could remember where was the fork hosted =/

[joeheyming]

Hey! My hacks are clean :-)!

But seriously, I wrote this so long ago, I probably would just rewrite it if I had time.

The web stuff for the emulator is now in a separate repository, so I've moved this to here. :) bfirsh/jsnes-web#20
