Web app manifest, first go

in

I've added a basic web app manifest to my site. I have not experimented with the results, but I did run it through a web manifest validator mostly to success. I used the MDN guide and the HTML5 doctor article for help. I also read some of the in-progress spec, though it seemed more implementer-friendly. The content of my manifest is currently (prettified):

{
	"background_color": "#4e784e"
	,"display": "browser"
	,"icons": [
		{
			"sizes": "64x64"
			,"src": "favicon.gif"
			,"type": "image\/gif"
		}
	]
	,"lang": "en-US"
	,"name": "Toby Mackenzie\u0027s site"
	,"scope": "\/"
	,"short_name": "\u003Ctoby\u003E"
	,"start_url": "\/"
	,"theme_color": "#4e784e"
}

I'm just using Symfony's JsonResponse object to render a PHP array.

This is one more thing that I really shouldn't've put time into until my site is more fleshed out, but it seemed cool and simple to add.
