* switched to miniJSON as Newtonsoft.Json doesn't work on webplayer
* webplayer page now uses javascript websockets to get blockchain data and passes it to Unity, c# implementations require a socket policy server to be running on the target machine when deploying to webplayer
* created a "quit" button for standalone
* anchored the buttons so they work better with different aspect ratios
* created two versions of the fireworks scene, one for webplayer without "Quit" button, perhaps a smarter way to do this is to just hide the quit button through code on webplayer builds, that way it doesn't require maintaining two versions of the same scene
