Number widget http_proxy plugin doesn't work

[fdietz]

As reported in the mailinglist:

I'd like to create a very simple number widget to display a value stored in a remote json.

Like :
www.example.com/foo.json

The json content would be for example :
{
"value" : 68999,
"label" : "Total count"
}

I don't know what to actually use as settings in the widget conf. I tried :
Source : http_proxy
proxy url : www.example.com/foo.json
Value : blank

I tested this for myself and it seems to work fine.

I've added more logging to simplify debugging though:
