If sending SlimJSON encoded data, SS 7.4 sends item IDs encoded as numbers, the versions before used strings.

This crashes iPeng.

Tested on r27258
This is true at least for albums

Also, if an item's text field in SlimBrowse menus (which definitely should be a string) is being encoded as a number if it contains a numeric value as is true for the "Years" menu.

The really funny thing about the latter one is that it this goes away when I enable debug.cometd!!!!!!
Could the debug setting have some influence on the actual SlimJSON processing on the server side?

Here's some of the (broken) data, as you can see, the "text" item is encoded as a number rather than a string as it definitely should be ("1964" here is supposed to be the string to display).

[
	{
		"data":{
			"base":{

...

				},
				"window":{
					"titleStyle":"years",
					"menuStyle":"album"
				}
			},
			"count":32,
			"item_loop":[
				{
					"params":{
						"favorites_title":0,
						"favorites_url":0,
						"year":0
					},
					"text":"Unknown"
				},
				{
					"params":{
						"favorites_title":1964,
						"favorites_url":"db:year.id=1964",
						"year":1964
					},
					"text":1964
				},
				{
					"params":{
						"favorites_title":1966,
						"favorites_url":"db:year.id=1966",
						"year":1966
					},
					"text":1966
				},
