[TIMOB-1600] Android: JSON.stringify incorrectly handles dates including silently faiing

Here is the output of JSON.stringify on a number of different platforms, including Android. As you can see, the Android version handles both a date directly incorrectly, and embedded in an object incorrectly, but differently.

This bug makes it very difficult to send date information to servers or store it in local state.

Firefox:
JSON.stringify(new Date()) => "2010-08-19T09:12:00.027Z" JSON.stringify({time: new Date()}) => {"time":"2010-08-19T09:13:30.025Z"}

Chrome:
JSON.stringify(new Date()) => "2010-08-19T09:14:16.527Z" JSON.stringify({time: new Date()}) => {"time":"2010-08-19T09:14:55.028Z"}

Titanium iPhone:
JSON.stringify(new Date()) => "2010-08-19T09:21:22.528Z" JSON.stringify({time: new Date()}) => {"time":"2010-08-19T09:21:22.528Z"}

Titanium Android:
JSON.stringify(new Date()) => "Thu Aug 19 10:19:00 Europe/London 2010" JSON.stringify({time: new Date()}) => {}
