Updates color scheme syntax

[s7726]

Here are the rules for the json color scheme syntax

		{
			"name": "Test PASS",
			"scope": "test.status.pass",
			"foreground": "#33FF33",
		},
		{
			"name": "Test FAIL",
			"scope": "test.status.fail",
			"foreground": "#FF3333",
		},
		{
			"name": "Test SKIP",
			"scope": "test.status.skip",
			"foreground": "#999999",
		},
		{
			"name": "Test TODO",
			"scope": "test.status.todo",
			"foreground": "#FFFF33",
		},

I don't know what version of ST uses the xml syntax, but this works for ST4. Easy way to add it is with the PackageDev package, ctrl+shift+p PackageDev: Edit current color scheme
